Gujarati phonology

Gujarati is an Indo-Aryan language native to the Indian state of Gujarat. Much of its phonology is derived from Sanskrit.

Phonotactical constraints include:

Gemination can serve as intensification. In some adjectives and adverbs, a singular consonant before the agreement vowel can be doubled for intensification. #VCũ → #VCCũ.

The matter of stress is not quite clear:

Schwa-deletion, along with a-reduction and [ʋ]-insertion, is a phonological process at work in the combination of morphemes. It is a common feature among Indo-Aryan languages, referring to the deletion of a stem's final syllable's /ə/ before a suffix starting with a vowel.

This does not apply for monosyllabic stems and consonant clusters. So, better put, #VCəC + V# → #VCCV#. It also doesn't apply when the addition is an o plural marker (see Gujarati grammar#Nouns) or e as an ergative case marker (see Gujarati grammar#Postpositions). It sometimes doesn't apply for e as a locative marker.

A stem's final syllable's /ɑ/ will reduce to /ə/ before a suffix starting with /ɑ/. #ɑC(C) + ɑ# → #eC(C)ɑ#. This can be seen in the derivation of nouns from adjective stems, and in the formation of passive and causative forms of verb stems.

Between a stem ending in a vowel and its suffix starting with a vowel, a [ʋ] is inserted. #V + V# → #VʋV#. This can be seen in the formation of passive and causative forms of verb stems.
