CHAPTER TWO VOWELS AND GLIDES
2.1 Syllable and mora in Japanese
2.1.1 The syllable
Because the syllable is the basic unit of segmental organization in all languages, many patterns of segmental distribution and evolution may best be understood within the context of syllable structure. The syllable may be characterized as an organization of segments in a sonority pattern. An utterance is a series of syllables sonority peaks surrounded by less sonorous satellite segments. Vowels, the most sonorous segments, typically serve as peaks, with obstruents, the least sonorous segments, as satellites. Liquids, nasals, and glides occupy intermediate positions between vowels and obstruents. Satellite segments which precede the syllable peak comprise the syllable onset, while those which follow the peak comprise the syllable offset. Perceptually the ideal syllable is characterized by maximum sonority at the peak and minimum sonority in the satellites. Coupled with the tendency toward open syllables (syllables with no offset) this may explain the universal presence in infant speech of combinations of the type [papa], [tata], [dada], [mama].
Japanese syllable structure approaches the ideal of vocalic peaks of sonority separated by relatively non-sonorous consonant onsets. There are more complicated canonical shapes as well (cf. Chapter 3) but the classic CVCV pattern prevails overall. Such a pattern offers maximum perceptual clarity, but lenition processes diminish this clarity in favor of ease of articulation. The tension between these two teleologies explains many of the contradictory developments in synchronic speech processing as well as in diachronic phonology. For example, all syllables have vocalic peaks in lexical representation, but the. application of vowel weakening processes (cf. Chapter 4) sometimes results in syllables with obstruent or nasal peaks on the surface e.g. /su.te.ki/ → [s.te.ki ] "nice', /uma/ → [m.ma] 'horse.'
Syllable structure influences the application of processes in various ways. For instance, other things being equal, onset segments are less likely to undergo lenition processing than offset segments, e.g. offset /n/ is subject to a number of assimilatory processes to which onset /n/ is immune:
|
(1) /tan.i/ → [tãã.i] 'unit' |
| (2) /ta.ni/ → [ta.ni] 'valley'
|
In (1) /n/ weakens under the influence of an adjoining vowel while in (2) it does not. (1) also illustrates the fact that the application of processes is often constrained by the presence of syllable boundaries. In Japanese the offset nasal segment will extend nasalization to the preceding peak but not to a segment of the following
syllable.
2.1.2 The mora
Most treatments of Japanese phonology fail to distinguish between syllable and mora. Hattori (1960 p. 247ff) discusses syllable structure, and McCawley (1968 p. 58ff) and Martin (1967 p. 246 and 1975 p. I-1 ff) clearly contrast the two. But all too frequently the terms 'syllable' and 'mora' are used interchangeably in reference to what is in fact the mora.
The mora concept arises in languages which make a distinction between long and short syllables, e.g. Japanese, Classical Latin, Classical Greek. A mora is a rhythmical unit of which short syllables have one and long syllables have two. The extra mora in long syllables is due to the presence of an offset segment. Thus in Japanese /a/, /ka/, /kya/ are short syllables and /aa/, /kaa/, /kyaa/, /kyan/ are long syllables. McCawley (1968), using terminology from Troubetskoy, has dubbed Japanese a 'mora counting syllable language,' by which he means that the syllable is the prosodic unit or bearer of pitch accent (i.e. there is no distinction between syllables accented on the first mora and syllables accented on the second mora), and the mora is the unit of phonological distance (i.e. accent rules are of the type 'place the accent on the antepenultimate moral). The example McCawley uses to show that both the syllable and the mora are necessary is the loan word /erebeetaa/ 'elevator' which in accordance with the above rule of accentuation of Japanese would be accented /erebeétaa/, but which in fact is accented /erebéetaa/ because long syllables are never accented on the second mora. The rule then must be worded 'place the accent on the syllable containing the antepenultimate mora.
There is other evidence that Japanese is a 'syllable language.' Ashworth and Lincoln (1973) cite verb stems derived from borrowed words which are shortened forms of the originals to which a native inflectional suffix is attached, e.g.
Table 2.1Foreign Verb Stems
| | Original | Verb stem | Non-past | |
1. | /a.dzi.tee.syon/ | /adzir-/ | /adziru/ | 'to agitate' |
2. | /de.mon.su.to.ree.syon/ | /demor-/ | /demoru/ | 'to demonstrate' |
3. | /haa.mo.nai.dzu/ | /hamor-/ | /hamoru/ | 'to harmonize' |
4. | /da.ben/(1) | /daber-/ | /daberu/ | 'to chat idly' |
To state the rule for deriving the verb stem from the original in 2, 3, and 4 it will be necessary to recognize not only the syllable but the difference between long and short syllables since the stem apparently must begin with two short syllables followed by /r/ even if the syllables in question were originally long. Thus the verb stem is formed on the first
two syllables (not moras) of the original minus any offset segments.
2.1.2.1 Mora duration
It is usually claimed (e.g. Han 1960) that in Japanese the moras in an utterance are of more or less equal duration, but spectrographic evidence (Wang 1968) shows that on the contrary the duration of moras differs widely depending on segmental constituency and other factors. Native speakers are aware of the number of moras in an utterance (or a line of poetry) and it is apparently length based on this quantity that they respond to rather than length measured in centiseconds. To the extent that the latter plays a role it is in the intention and perception of speech rather than its actuation.
2.1.2.2 Mora and the Kana Orthography
The confusion between the syllable and the mora in Japanese may derive to some extent from the 'syllabic' kana orthography with which the language is written. At its inception the kana orthography was, indeed, syllabic since there was apparently no distinction between long and short syllables in Old Japanese (OJ). Subsequent developments introduced such a distinction however, and today the kana orthography would be better termed 'moraic.'
2.2 Vowels
In her study of the natural phonology of vowels Donegan (1978) distinguishes three basic identifying vowel
features palatality, labiality, and sonority.(2) A cover term for the features palatality and labiality is color (timbre), and vowels with the palatal and/or labial feature are, chromatic vowels. The relationship between color and sonority is such that vowels with a high degree of one will have a low degree of the other:
| PALATALITY | | LABIALITY |
| i | ɨ | u |
| e | ʌ | o |
| æ | a | ɔ |
| | SONORITY | |
|
2.2.1 Context-free Vowel Processes
Donegan also proposes a number of universal context-free processes which account for the commonly occurring vowel substitutions in natural languages. Included are the following apparently contradictory pairs of processes: Raising Lowering; Bleaching (depalatalization or delabialization) Coloring (palatalization or labialization); and Tensing Lazing. Raising, Coloring, and Tensing increase color and Lowering, Bleaching and Lazing increase sonority. Although the pairs of processes have contradictory teleologies, the fact is that only one member of the pair tends to apply under given phonetic conditions.
2.2.1.1 Raising
Raising tends to apply to chromatic vowels, especially lower ones, while Lowering tends to apply to achromatic vowels, especially higher ones:
| [+ PAL] | | [- PAL] [- LAB] | | [+ LAB] |
| ↑ i | | ↓ ɨ | | ↑ u |
| ↑ e | | ↓ ʌ | | ↑ o |
| ↑ æ | | ↓ a | | ↑ ɔ |
|
2.2.1.2 Bleaching
Bleaching is more likely to apply to lower chromatic vowels:
| [+ PAL] | | [- PAL] [- LAB] | | [+ LAB] |
| i →→ | | ɨ | | ←← u |
| e →→→→ | | ʌ | | ←←←← o |
| æ →→→→→→ | | a | | ←←←←←← ɔ |
|
2.2.1.3 Coloring
Coloring tends to apply to higher achromatic vowels:
| [+ PAL] | | [- PAL] [- LAB] | | [+ LAB] |
| i | ←←←←←← | ɨ | →→→→→→ | u |
| e | ←←←← | ʌ | →→→→ | o |
| æ | ←← | a | →→ | ɔ |
|
A characteristic of any process is that the application of its subprocesses reflects a strict implicational hierarchy such that for instance Coloring never applies to a lower achromatic unless it applies to higher ones (e.g. ʌ → e implies ɨ → i), or Lowering never applies to a mid achromatic vowel unless it applies to a high one as well (e.g. ʌ → a implies ɨ → ʌ). Since context-free processes in NP act in the manner of morpheme structure rules in generative phonology the hierarchical conditions on the application of processes governing the lexicon account for the fact that certain vowels (e.g. /ɨ, æ ,ɔ/) are frequently absent from underlying inventories.
2.3 Japanese Underlying Vowels
Japanese has the following five lexical vowels:
Table 2.2Japanese Lexical Vowels
| | [+ PAL] | [- PAL] [- LAB] | [+ LAB] |
| [+ HIGH] | i | | u |
[- HIGH] [- LOW] | e | | o |
| [+ LOW] | | a | |
From the absence of low chromatic vowels we can infer that Raising or Bleaching govern the lexicon. Likewise, the absence of the less sonorous achromatics implies that Lowering or Coloring also govern the lexicon. There is diachronic evidence for the raising of (long) low chromatic vowels. OJ [au̯] underwent monophthongization to [ɔɔ̯] (Nishihara 1970). We can assume [ai̯] > [ææ̯] as well since this latter remains in certain dialects (e.g.
Hiroshima prefecture according to Itoo (1979)), but in the standard language these monophthongs were raised to [oo̯] and [ee̯] respectively.
Loan phonology furnishes further evidence of vowel processes that govern the lexicon. Lovins (1973) cites a number of correspondences between foreign vowels and their Japanese cognates, e.g.
Table 2.3Foreign Vowels and Their Japanese Cognates
| Foreign | Japanese | Process | Example |
| /ɔ/ | o | Raising | /ooto/ 'auto' |
| /ʌ/ | a | Lowering | /rabu/ 'love' |
| /æ/ | a | Bleaching | /batto/ 'bat' |
| /ə/ | a | Lowering | /saakasu/ 'circus' |
(See Lovins ibid. p. 72ff for discussion of exceptions due to orthographic influence and other reasons.)
2.3.1 Vowel length
As is typical of mora-counting languages, vowel length in Japanese is distinctive, and all five vowels occur in both long and short varieties. Long vowels will be written as a vowel plus homorganic glide sequence (VV̯), the vowel representing the syllable peak and the homorganic glide the offset e.g.
| /ki/ 'tree' | | /kii̯/ 'strange' |
| /me/ 'eye' | | /mee̯/ 'niece' |
| /obasan/ 'aunt' | | /obaa̯san/ 'grandmother' |
| /ku/ 'nine' | | /kuu̯/ 'emptiness' |
| /ko/ 'child' | | /koo̯/ 'this way' |
Although for convenience long vowels are here written as two segments there is evidence, both diachronic and synchronic, that they are in fact unitary. Historically long vowels have not undergone diphthongization as might be expected if they were structurally bipartite (cf. Donegan 1978, p. 56). What changes they have undergone e.g. raising [ææ̯] > [ee̯] have affected the long vowel as a whole. There is also evidence from synchronic speech processing. Martin (1974) cites a game called sakasa kotoba 'upside-down words' (also the source of a special language referred to as yakuza kotoba 'gangster argot') which requires that the first and last portions of words be reversed, e.g. /kore/ → /reko/. Table 2.4 contains examples involving long vowels and other syllables:
Table 2.4'Upside-down Words'
| | Original | Reversed |
| 1. | /tai̯ra/ 'Pr Name' | /rai̯ta/ |
| 2. | /kappu/ 'cup' | /pukka/ |
| 3. | /ringo/ 'apple' | /gonri/ ~ /gorin/ |
| 4. | /gindza/ 'Ginza' | /dzangi/ ~ /dzagin/ |
| 5. | /byoo̯bu/ 'screen' | /bubyoo̯/ |
| 6. | /tii̯dzu/ 'cheese' | /dzutii̯/ |
Where long syllables are involved the syllable is divided if it contains a diphthong (example 1) or an offset nasal (examples 3 and 4). However, it is never divided if it contains a long vowel (examples 5 and 6).
Long vowels may also arise on the surface in lenited speech due to the application of the process Vowel Coalescence (cf. §4.1.4) to a sequence of identical vowels in adjacent syllables e.g. [suu.ri] 'vinegar vendor' (< /su/ 'vinegar' /uri/ 'sell').
2.3.2 Diphthongs
A diphthong is a syllable nucleus with two vowel segments only one of which is syllabic. The non-syllabic may come from an adjoining consonant which is weakened e.g. z > y, b > w; or from an adjoining vowel which loses its syllabicity e.g. i > y, u > w. Diphthongs may also arise from simple vowels (Donegan 1978 p. 111) but such a development seems not to have occurred in Japanese. in ongliding diphthongs the non-syllabic precedes the syllabic e.g. [ya, wa]. In off-gliding diphthongs the non-syllabic follows the syllabic e.g. [ai̯, au̯]. In mora-counting languages such as Japanese an off-gliding diphthong constitutes a long (i.e. two-mora) syllable.
2.3.2.1 On-gliding diphthongs
OJ had the following on-gliding diphthongs (Martin 1976):
| ye, ya, yo, yu |
| wi, we, wa, wo |
Due to the gradually more general application of processes eliminating prevocalic glides SJ now has only:
and [wa] alternates with [a] in hypoarticulate speech
(cf. Chapter 4). The loss of the labial glide before vowels occurred in the following historical order: earliest before the palatal vowels /i,e/ (where it apparently shifted to /y/ which was itself subsequently lost (Martin 1975); next before /o/ (this is a recent development); and last before /a/ where it is now optionally fronted or deleted depending on the environment. The following two processes account for these developments:(3)
| (P1) GLIDE FRONTING: W → Y / ___ | [ V [ - lab [ ! higher | ] ] ] |
Before /i,e/ this process governs the lexicon assuring */wi, we/. Before /a/ and preceded by a palatal vowel it optionally governs surface structure accounting for [iwa, ewa) → [iya, eya) e.g. /i wa sinai/ → [i ya sinai] 'it is not found', /kore wa/ → [kore ya] 'this (topic)'. The application of this subprocess of P1 is most frequent where the topic marker 'wa' is involved.
| (P2) PRE VOC LAB GLIDE DEL: W → Ø / ___ | [ V [ - pal [ ! higher | ] ] ] |
Before /u,o/ this process governs the lexicon assuring */wu,wo/. Before /a/ application is constrained as follows:
(i) Preceded by a non-palatal vowel it optionally governs surface structure e.g. /boku wa/ → [boku a] 'I (topic)', /soko wa/ → [soko a] 'there (topic)', /siawase/ → [s̆iaase] 'happiness'.
(ii) Preceded by # (word boundary) it usually does not apply e.g. /waza waza/ → *[aza aza ]. (Note however [atas̆i], a female speech version of [watas̆i] 'I').
The loss of /ye/ was due to the palatal counterpart of LAB GLIDE DEL and is accounted for by the following process:
| (P3) PRE VOC PAL GLIDE DEL: Y → Ø / ___ | [ V [ + pal [ ! higher | ] ] ] |
(P1), (P2), and (P3) together assure */yi, ye, wi, we, wu, wo/. The effects of (P2) and (P3) can be seen in loan phonology. The following data is from Lovins (1973 p. 97):
| /iisuto/ | 'yeast' |
| /eroo/ | 'yellow' |
| /uuru/ | 'wool' |
| /ikooru/ | 'equal' |
In Chapter V alternate forms of these loan words are discussed.
The 'mirror image' of PRE VOC PAL GLIDE DEL applies optionally in hypoarticulate speech to delete [y] after palatal vowels before non-palatals as in [iyoo̯] → [ioo̯] 'let's stay' (cf. §4.2.3).
Although there is diachronic evidence for Glide Fronting, at least before /e/, synchronic evidence is difficult to come by due to */yi, ye/. However there are some hypoarticulated forms which show its effects, e.g.
| /inoue/ → [inouwe] → [inouye] 'Proper Name' |
| /nihon e/ → [nihõõ e] → [nihõõ we] → [nihõõ ye]
'to Japan' |
The /w/ in these forms arises from application of Glide Epenthesis, a fortition process described in §2.3.3. It is not unusual for sequences which are lexically inadmissible (e.g. [we] and [ye] in these examples) to be created on the surface in hypoarticulate speech processing. Stampe (1973) gives the example of the hypoarticulate form [bniθ] 'beneath' which violates the lexical constraint in English against initial stop-nasal clusters.
2.3.2.2 Off-gliding diphthongs
There is general agreement that the off-gliding diphthongs in SJ are [ai̯, ei̯, oi̯, ui̯] (Hattori 1960, Martin 1975, McCawley 1968) with Martin adding [au̯] as a possibility in loan words. But the phonetic basis for these assertions is not clear. Martin (1967) gives only 'morphophonemic' status to bi-moric syllables saying they have 'nothing to do with any assumed physiological manifestations (p. 247).' Later however (Martin 1975) he says the notion of the bi-moric syllable is based on 'auditory impression and on accent behavior; it is assumed that experimental phonetic investigations will prove the existence of an articulatory (motor-production) unit that corresponds to these ... syllables (p. I-2).' If we assume bi-moric syllables with two vowel qualities (i.e. off-gliding diphthongs) then one of the vowels must be [+ syllabic] (the peak) and one [- syllabic] (the offset). It follows that the well-known constraint that only the first mora of a long syllable can bear the accent (McCawley 1968) is due to the fact that accent must fall on the syllable peak. In [tadáI̯ma] 'right now' (< [táda] 'just' + [íma] 'now') the accent shift is a prerequisite to considering to be a diphthong what was originally two separate vowels. In /siíru/ 'to force' the location of the accent shows the /i/'s are not tautosyllabic. (Cf. Martin (1975 p. 24-5) for a relevant discussion of verb accentuation.
A criterion for assigning two vowel qualities to the same syllable might be their joint participation in processes such as monophthongization. Historically the substitutions [ai̯, ei̯, oi̯,] > [ee̯] have occurred in at least some dialects, and the same may be said for [au̯, ao̯, ou̯] > [oo̯] and for [e̯] > [yoo̯]. In the discussion below vowel sequences which form the input to processes of this sort are assumed to be off-gliding diphthongs.
In the history of Japanese, intramorphemic vowel sequences arose from diachronic developments of the type CVCV > CVV where the elided consonant included among others the palatal and labial glides discussed in §2.3.2.1. The resulting vowel sequences plus subsequent diachronic and synchronic vowel sandhi developments, if any, are indicated below. It will be seen that the same processes are involved in diachronic and synchronic substitutions, the different effects being due to limitations on the application of the process in one case but not the other. (All diachronic evidence cited in 1-20 below is from Martin 1976.)
/Vi̯/ Sequences: |
| 1. | /ei̯/ | virtually non-occurring in ModJ due to /ei̯/ > /ee̯/ which governs the lexicon for most speakers. e.g. /sensei̯/ > /sensee̯/ 'teacher'; also applies in loan phonology (cf Chapter 5). |
| 2. | /ai̯/ | occurs in ModJ. Diachronic evidence for /ai̯/ > /ææ̯/ >/ee̯/. Merges with /ae̯/ in hypoarticulate speech (cf Chapter 4) and in some dialects (cf Iitoyo 1976, p. 272 ff). |
| 3. | /oi̯/ | occurs in ModJ. Diachronic evidence for /oi̯/ > /ee̯/. Merges with /oe̯/ in hypoarticulate speech. |
| 4. | /ui̯/ | occurs in ModJ. Merges with /ii̯/ in
hypoarticulate speech. |
| /Vu̯/ Sequences: |
| 5. | /ou̯/ | virtually non-occurring in ModJ due to /ou̯/ >
/oo̯/ which governs the lexicon for most speakers.
e.g. /kou̯/ > /koo̯/ 'this way'. Also applies in loan phonology. |
| 6. | /au̯/ | non-occurring (except in recent loans) in ModJ morphemes due to /au̯/ > /oo̯/ e.g. /siyau̯/ > /siyoo̯/ 'a method'. |
| 7. | /eu̯/ | non-occurring in ModJ due to /eu̯/ > /yoo̯/ e.g. /keu̯/ > /kyoo̯/ 'today'. |
| 8. | /iu̯/ | occurs in ModJ though there is diachronic
evidence (e.g. /yorosiku/ > /yorosiu̯/ > /yorosyuu̯/ 'good') and synchronic evidence
(cf Chapters 4 and 5) for /iu̯/ > /yuu̯/. |
|
/Ve̯/ Sequences: |
| 9. | /ae̯/ | occurs in ModJ though there is diachronic evidence for /ae̯/ > /ee̯/ (e.g. /temae̯/ > /temee̯/ 'you' in some dialects). |
| 10. | /oe̯/ | occurs in ModJ. |
| 11. | /ue̯/ | occurs in ModJ. Evidence for [ue̯] → [ (w)ee̯] in hypoarticulate speech and loan words. |
| 12. | /ie̯/ | occurs in ModJ though there is diachronic evidence for /ie̯/ > /ee̯/ e.g. /kie̯ru/ > /kee̯ru/ 'to be extinguished' (Hiroshima dialect) and evidence in hypoarticulate speech for [ie̯] → [(y)ee̯]. |
| /Vo̯/ Sequences: |
| 13. | /ao̯/ | occurs in ModJ though there is diachronic evidence for /ao̯/ > /oo̯/ e.g. /mao̯su/ >
/moo̯su/ 'to say'. |
| 14. | /uo̯/ | occurs in ModJ. There is evidence in hypoarticulate speech and loan words for [uo̯] → [(w)oo̯] |
| 15. | /io̯/ | occurs in ModJ. There is evidence in
hypoarticulate speech for [io̯] → [yoo̯]. |
| 16. | /eo̯/ | non-occurring in ModJ due to /eo̯/ > /yoo̯/ e.g. /meo̯to/ > /myoo̯to/ 'husband and wife'. |
/Va̯/ Sequences:
There are no Va sequences from diachronic developments. The few occurrences in ModJ are due to recent loans. |
| 17. | /ia̯/ | e.g. /kasimia̯/ 'cashmere' but there is evidence for /ia̯/ → /iya/ e.g. /siberiya/ ~ /siberia̯/ 'Siberia', /itariya/ ~ /itaria̯/ 'Italy' and many such pairs. Also school children are known to have spelling difficulty with the distinction. There is also evidence for /ia̯/ → /ya/ e.g. /syamu/ 'Siam' (Lovins 1973 p. 98). There is some diachronic evidence for /ia̯/ > /e/ e.g. /kiyasu/ > /kia̯su/ > /kesu/ 'to erase'. |
| 18. | /ea̯/ | e.g. /sukuea̯/ 'square' but there is evidence for /ea/ → /eya/ e.g. /hea̯/ ~ /heya/ 'hair', /hurea̯/ ~ /hureya/ 'flare' (Lovins ibid p. 77). |
| 19. | /oa̯/ | e.g. /doa̯/ 'door', /sukoa̯/ 'score'. |
| 20. | /ua̯/ | e.g. /manikyua̯/ 'manicure', /amatyua̯/ 'amateur'. |
2.3.2.2.1 Types of off-gliding diphthongs
Typologically the sequences in 1-16 may be divided into three groups of off-gliding diphthongs:
| (I) | Up-gliding diphthongs not of mixed color: /ei̯, ai̯, ou̯, au̯, ae̯, ao̯/. |
| (II) | Up-gliding or level diphthongs of mixed color: /oi̯, ui̯, eu̯, iu̯, oe̯, eo̯/. |
| (III) | Down-gliding diphthongs: /ie̯, io̯, ue̯, uo̯/. |
Historical and dialectal evidence indicates that where
the non-syllabic, was higher than the syllabic (an up-gliding diphthong), the non-syllabic sought the height of the syllabic. I will account for this development by the process
| (P4) PROGR HT ASSIM: |
[ V̯ [ n height |
] ] |
→ [ n - 1 ] / |
[ V [ m height |
] ] |
_____ |
| | Condition: n higher than m |
Where the vowel was low and the glide high, the assimilation presumably occurred in two steps through iterative application of the process:
| Group I |
ei̯ > ee̯
ou̯ > oo̯
ai̯ > ae̯ > aæ̯
ae̯ > ae̯ >aæ̯
au̯ > ao̯ > aɔ̯
ao̯ > ao̯ > aɔ̯
|
| Group II |
oi̯ > oe̯
eu̯ > eo̯ |
The sequences involving low achromatic vowels were then subject to
| (P5) VOWEL COLORING: |
[ V
[ - color |
] ] |
→ [ α color] / ____ |
[ V [ α color |
] ] |
| e.g. aæ̯ > ææ̯ |
| e.g. aɔ̯ > ɔɔ̯ |
[ɔɔ̯] < [au̯] is attested in MidJ (Nishihara 1970) and
was subsequently raised to [oo̯]. [ææ̯] is attested in some ModJ dialects (Itoo 1979, Iitoyo 1976) but in SJ was raised to [ee̯].
For Group I sequences the result of these developments was monophthongization which effected the mergers
ai̯
ae̯ > ee̯
ei̯ |
|
au̯
ao̯ > oo̯
ou̯
|
Group II sequences underwent further change by Syllabicity Reversal, a process which applies to off-gliding diphthongs whose non-syllabic is not higher than its syllabic:
| (P6) SYL REV: |
[ + syll
[- cons
[ n ht
|
] ] ] |
[ - syll
[ - cons
[ m ht
|
] ] ] |
→ |
[ - syll
[ - cons |
] ] |
[ + syll
[ - cons
[ + long
|
] ] ] |
|
Condition: m not higher than n |
The [+long] syllabic on the right side of the arrow is written VV̯ in accordance with the convention proposed in §2.3.2, e.g.:
oe̯ > o̯ee̯
eo̯ > e̯oo̯
ui̯ > wii̯
iu̯ > yuu̯ |
The resulting non-high onset glides underwent Raising (the same process proposed in §2.2.1.1 for vowels). Glides are tenser and more chromatic than their homorganic vowels and so are even more subject to Raising. This implicational relationship (i.e. the raising of vowels implies the raising of homorganic glides) establishes that the same process is involved. The following formulation is from Donegan (1978) with a slight revision to include glides:
| (P7) RAISING: |
[! - cons
[! n high
[! + chromatic
[! + tense
[! lower
|
] ] ] ] ] |
→ [n + 1 high] + tense |
| (! = especially) |
| e. g. | o̯ee̯ → wee̯ |
| | e̯oo̯ → yoo̯ |
[wee̯] was then subject to Glide Fronting and Palatal Glide Del: [wee̯] → [ yee̯ ] → [ ee̯ ].

2.3.2.2.2 Derivation vs. Borrowing
Stated in their most general form processes often define the goal of a sound change in progress and provide a principled account of the relationship between various dialects in terms of evolution toward that goal. However processes do not always apply in their most general form, and sound changes frequently stop short of completion e.g. there are many [ai̯] sequences which did not monophthongize or which did so only in some dialects. Generative treatments (e.g. Hasegawa 1979, Slawson 1970) often note that only certain lexical items are subject to the 'ai̯, oi̯, ae̯ → ee̯ rule' and that there are certain social constraints on its application. Consider the following pairs from Hasegawa (ibid p. 129)
| 1. | /atarimae̯/ | | /atarimee̯/ | 'of course' |
| 2. | /nai̯/ | | /nee/ | 'negative suffix' |
| 3. | /sugoi̯/ | | /sugee̯/ | 'terrific' |
| 4. | /koi̯tu/ | | */kee̯tu/ | 'this man' |
| 5. | /sai̯go/ | | */see̯go/ | 'the last' |
| 6. | /kimae̯/ | | */kimee̯/ | 'generosity' |
The forms on the left occur in SJ. The use of the right hand forms in examples 1, 2, and 3 by standard speakers is restricted to males. The impression is dialectal or slangy. The right hand forms in examples 4, 5, and 6 do not occur at all in standard speech. Under the circumstances it seems clear that the [ai̯] [ee̯] alternation in the above pairs is no longer a phonetically motivated substitution. The alternants are equally pronounceable by standard speakers and are not sensitive to rate of speech or other factors which might suggest phonetic motivation. For SJ the source of the right hand forms is interdialectal borrowing, not derivation by processes from the forms on the left. In Chapters 4, 5, and 6 evidence from hypoarticulate speech, loan phonology, and Hawaiian Japanese, respectively, will be examined to throw light on the synchronic status of these processes.
The down-gliding diphthongs in §2.3.2.2.1 labelled Group III (i.e. [ie̯, io̯, ue̯, uo̯] do not seen in general historically to have undergone SYL REV though they meet the input conditions as formulated for that process. (The example /kie̯ru/ > /kee̯ru/ in §2.3.2.2 is an example however.) Apparently SYL REV applied primarily to sequences where the syllabic and non-syllabic were the same height, as in Group II. However, we shall see that the application of SYL REV does include down-gliding diphthongs in hypoarticulate speech (cf Chapter 4) and loan words (cf Chapter 5).
2.3.3 Glide Epenthesis
Besides the lenition processes so far considered in this chapter there are also fortition processes which act to eliminate vowel sequences and restore a CVCV pattern. Glide Epenthesis is an optional fortition which interposes a non-syllabic between two vowels. This prevents the lenition of vowels in a sequence thus maximizing perception, the typical result of fortition processing.

Examples:
| 1. /siawase/ → [siyawase] 'happiness' |
| 2. /sio/ → [siyo] 'salt ' |
| 3. /iu/ → [iyu] 'to say' |
| 4. /kore o/ → [koreyo] ' this (accusative)' |
| 5. /o atuu̯/ → [owatsuu̯] 'hot (honorific)' |
The application of Glide Epenthesis can result in mergers of the following sort:
| 6. | /kioo̯/ 'the past' → [kiyoo̯] (merges with /kiyoo̯/ 'dexterity'). |
| 7. | /kare ni aru/ 'belongs to him' → [kare ni yaru] (merges with /kare ni yaru/ 'give to him'). |
| 8. | /uti ni oru/ 'be at home' → [utsi ni yore]
(merges with /uti ni yoru/ 'call at home'). |
| 9. | /o ari desu ka/ 'does it exist?' → [owari des ka] (merges with /owari desu ka/ 'are you finished?' ) |
NOTES
(1) daben 'idle chat' is a Sino-Japanese compound.
(2) I owe such of my understanding of vowel processes to Donegan (1978) and (Donegan) Miller (1972, 1973).
(3) The notation used in the formalization of processes will be alphabetical where no sacrifice in clarity will result. Where feature notation is used it will vary from cover terms such as 'glide,' 'height,' 'color' to the feature terms themselves. In all cases the allusion is to articulatory gestures. The notational device '!' (read 'especially') is from (Donegan) Miller (1972). The feature matrix for consonants will appear in Chapter III. That for vowels and glides is as follows:
| | i | e | a | o | u | | y(i̯) | e̯ | a̯ | o̯ | w(u̯) |
| cons | - | - | - | - | - | | - | - | - | - | - |
| syll | + | + | + | + | + | | - | - | - | - | - |
| pal | + | + | - | - | - | | + | + | - | - | - |
| lab | - | - | - | + | + | | - | - | - | + | + |
