The passive has both periphrastic and morphological means of expression. The former has -mā̃ āvvũ postpositioned to infinitive; the latter has ā added to root, with certain phonological processes as work as well: if the root vowel is ā then it becomes a (See Gujarati phonology#ɑ-reduction) and if the root ends in a vowel then h or v is suffixed. Thus lakhvũ "to write" → lakhvāmā āvvũ, lakhāvũ "to be written". The post-position thī marks the agent, As in other New Indo-Aryan languages, formation of passives is not restricted to transitive verbs and has a restricted domain of usage except in special registers. Both intransitive and transitive may be grammatically passivized to show capacity, in place of compounding with the modal śakvũ "to be able". Lastly, intransitives often have a passive sense, or convey unintentional action.
