Archi is spoken in mountainous areas of the
southern Dagestan ASSR, in the Soviet Union. Kodzasov
(1977) treats pharyngealization as a 'suprasegmental'
element which can be focussed on a vowel or a uvular
consonant. Particularly in the latter case it seems
preferable to treat it as segmental. Originally only velar
and uvular consonants (and the long lateral fricative ?)
had contrastive labialization but there are now a few
words with distinctive labialization on most of the
dental/alveolar or palato-alveolar obstruents. The voiced
lateral fricative arises from morphological combination of
a lateral ejective and a dental/alveolar stop but surface
contrasts occur with other laterals.
