3.2.1.3 jat

(e
ˇ)
The table of Proto-Slavic vowel phonemes in 3.2.1 makes /e
ˇ
/ look well integrated as
a front partner to /a/. But the reality is that the [a
¨
] position became unstable after
the developments which led to phonemicization of palatalization. In the former
opposition of hard soft syllables, it was the vowel which was dominant, for
example in the opposition of, say, /ta/ to /t
0
a
¨
/. The back front distinction resided
mainly in the vowel, supported by the hard or soft nature of the consonant. After
the loss of the jers and the closing of syllables, the bond between the consonant and
vowel was weakened and the single segments became phonemic. In this situation it
was the consonants which became dominant within the system, since they were
‘‘independently’’ phonemic, for example in final position where no vowel followed.
In the new syllables /t-a/ and /t
0
-a
¨
/ the quality of the vowel was secondary, and since
in the context of simple phonetics the distance between /a/ and /a
¨
/ is small and fragile,
/a
¨
/ readily came to be seen as an allophone of /a/. Thus Proto-Slavic /e
ˇ
/ found itself
losing independence. But in several areas it appears to have ‘‘defended itself’’, so to
speak, in the short term by shifting to a higher position, in the extreme case (Ukr)
ending up as /i/, while original /i/ there moved back to /y/. Former /e
ˇ
/ is now nowhere
a separate phoneme, and is directly traceable only in the jekavski (Jekavian) variant
of B/C/S, where it is reflected in the phonemic sequences /j-e/ or /i-j-e/. Elsewhere it
has coalesced with some other phoneme – most often /e/, sometimes /a/. In the case of
Ukrainian it was joined in the /i/ position by new /i/ from other sources (3.2.1.5).
A different view about the systemic weakness of /e
ˇ
/ is that, unlike the other
phonemes, it was phonetically still a complex sound, effectively a rising diphthong
of the /ea-ia/ type (Shevelov, 1964: 585). Its complexity within an otherwise ‘‘pure
vowel’’ system was therefore its weakness. This does make the actual range of shifts
easier to understand. The phonetic nature of /e
ˇ
/ at the end of Proto-Slavic is open
to debate, and the phonemic scenario described in the preceding paragraph can
equally well account for its subsequent fate, since the end point of push–pull
activity is not necessarily phonetically predictable. So we shall simply note the
fact of its weakness and observe its reflexes, which must also be related to the rest of
each given vocalic system (examples are given in table 3.3).

It is probably no coincidence that the areas which initially ‘‘retained’’ /a

/ (but
where it later became /a/) were those which also retained nasality, on the grounds
