There could well have existed an Extension of Sievers’ Law before consonantals and before a
pause if –as the surviving difference betweenGreek(Attic-Ionic) (´op
h
ra) “in order that”
(with one short vowel and one consonant preceding) and (hˆepar) “liver” (with one
long vowel and one consonant preceding) suggests – the allophonic notation
∗
[r] stands for
two quite distinguishable allophonic entities:
∗
[r
e
], with (it may be imagined) increasingly
prominent syllabicity (in ); and
∗
[
e
r], with syllabicity decreasing to the rightward
(in ).
In word-initial syllables where the determining environment is not built in, one would
expect vacillation between [ra] and [ar], with a potential for mutual analogic exchanges and
generalizations. This is indeed what one finds: for example, in Homeric (krad´ı¯e)
beside (kard´ıa) “heart.”
In Greek, as in other descendant languages, this
∗
[
e
] adjacent to liquids and nasals became
phonemic by merging with some existing vowel (in Attic-Ionic with [a]). In the case of
Indo-European
∗
[y/i] and
∗
[w/u] (these from the oldest period), and (much later) Indo-
Iranian
∗
[r/r] (Sanskrit . . . /r [but
∗
[r] > Sanskrit ir before vocalics (..aktira..) under Sievers’
Law proper; i.e., not the Sievers’ Law “Extension”], Avestan . . . /
ərə), the three pairs of two
positional variants are transformed into one segment each, perhaps of steady (i.e., neither
increasing nor decreasing) vowel-like quality. Under similar circumstances [
e
] in the vicinity
of obstruents can end up phonemic in the descendant languages by merging with one of
the existing vowels, though here the data remain shadowy. As a result of all of this, overlong
syllables (short vowels with more than two consonants, or long vowels or diphthongs with
two consonants before the next vowel) are rare, for example in Vedic and in Greek, until
sound changes create new overlengths (see Hoenigswald 1994 for the details; lengthened
grade [see §3.2] in certain formations is [still?] extremely rare in Sanskrit before consonant
clusters; see Debrunner 1954:61).

2.5 Word boundaries
Word boundaries (i.e., seams between so-called minimum free forms; see Hoenigswald
1992) loom large as conditioning factors in sound changes. So far from indicating, however,
that all word boundaries are phonologically marked and contrast with Ø in word-interior
position (note §2.4 on phonetic conditioning across a word boundary), word boundary is
best considered an analogical development made possible by the circumstance that pause
(the absence of sound which contrasts with the presence of sound, a universal condition) is
an option at word boundaries. Post-pausal and ante-pausal allophony was generalized and
turned into apparent word-initial and word-final phonology, each contrasting with word-
interior phonology. The descendant languages differ somewhat in the extent to which this
analogic change is carried through. Where analogic generalization is complete, utterances
may indeed be treated as “composed of ” (rather than “analyzed into”) words in external
sandhi (some of the sandhi phenomena of Insular Celtic may be relevant survivals – see
Russell 1995; sandhi phenomena were, however, created again and again in the separate
branches).
2.6 Accent
The fragmentary character of the scripts in which the texts of the descendant languages
are recorded, combined with the neglect of relevant phenomena despite their syntactic
