<p>In this paper I describe bilingual complex verb constructions in Bengali-English bilingual speech. Bilingual complex verbs have been shown to consist of two parts, the first element being either a verbal or nominal element from the nonnative language of the bilingual speaker and the second element being a helping verb or dummy verb from the native language of the bilingual speaker. The verbal or nominal element from the non-native language provides semantics to the construction and the helping verb of the native language bears inflections of tense, person, number, aspect (Romaine 1986, Muysken 2000, Backus 1996, Annamalai 1971, 1989). I describe a type of Bengali-English bilingual complex verb which is different from the bilingual complex verbs that have been shown to occur in other codeswitched Indian varieties. I show that besides having a two-word complex verb, as has been shown in the literature so far, bilingual complex verbs of Bengali-English also have a three-part construction where the third element is a verb that adds to the meaning of these constructions and affects their aktionsart (aspectual properties). I further show that monolingual Bengali complex verbs directly contribute to the rise of these bilingual complex verbs.</p>
