definition of active voice
For active and passive in English, see English passive voice. Active voice is a grammatical voice common in many of the world's languages. It is the unmarked voice for clauses featuring a transitive verb in nominativeâaccusative languages, including English and most other Indo-European languages. Active voice is used in a clause whose subject expresses the main verb's agent. That is, the subject does the verb's designated action. A clause whose agent is marked as grammatical subject is called an active clause.
