represent the reflex of an Indo-European labiovelar
or pure velar, belonging most probably to either the voiceless or voiced unaspirate series (hence, IE *, *[k.
The voiceless labiovelar fricative *[chi]w lost its rounding in root final position at some point, probably as early as the Northwest Germanic stage, and appeared in Old English as h or was eventually dropped.
When the voiced labiovelar fricative [v], produced by medial voicing, merged with *[[beta]] (as [v]), a new phonemic contrast arose, namely /f/ vs.
With respect to the appearance of /h/ before glides in American English, many speakers no longer have the /hw/ sequence in words like what and where (and even for those that do, it is unclear as to whether it should be analyzed as a sequence or a single sound, namely as a voiceless labiovelar
3) The Lydian letter + has been interpreted as either a bilabial stop /p/ or a labiovelar
Just as in the case of other Germanic dialects, the traces left in Old English evince undeniably the application of the rule only in the case of palatal glide (i/i), not even the labiovelar one (u/u).
In fact Sievers' rule assumed parallel alternation for both semivowel phonemes: palatal /j/ and labiovelar /w/; the latter however seems less relevant to Germanic which preserves essentially no traces of its alternation.
134): Hittite kuiski cannot go directly with Latin quisque without explaining the absence of the labiovelar
in the second syllable.
if there is a connection, the apparent labiovelar
(note the Mycenacan q-sign) might conceivably come from something like * (a)sku-V-.
I assume that in the Qieyun it was a labiovelar
glide, w, which only occurred before the high vowels -i- and -u- and which was lost before the resulting -i- or -y- (Pulleyblank 1984: 164-67).
Linguists have been able accurately to predict the existence of undocumented aspects of archaic languages (like certain labiovelars
in Mycenaean Greek) prior to their discovery in ancient inscriptions (Bynon 1977: 72).
I agree with the author that the labiovelars
are phonemic and did not necessarily develop "from plain velar consonants in the presence of rounded vowels o, u.
