This paper presents the automatic ex-traction of Complex Predicates (CPs) in Bengali with a special focus on compound verbs (Verb + Verb) and conjunct verbs (Noun /Adjective + Verb). The lexical patterns of com-pound and conjunct verbs are extracted based on the information of shallow morphology and available seed lists of verbs. Lexical scopes of compound and conjunct verbs in consecutive sequence of Complex Predicates (CPs) have been identified. The fine-grained error analysis through confusion matrix highlights some insufficiencies of lexi-cal patterns and the impacts of different constraints that are used to identify the Complex Predicates (CPs). System achieves F-Scores of 75.73%, and 77.92 % for compound verbs and 89.90 % and 89.66 % for conjunct verbs respectively on two types of Bengali corpus. 1
