As in the case of adjective and locative phrases, the occurrence of the copula in front of predicative noun phrases is variable in Bahamian Creole English. The form is usually is, regardless of person and number, even though am and are occur as well. All three forms are usually contracted. Of the three following grammatical environments adjective phrase, locative phrase, and noun phrase, copula absence is rarest with noun phrases (cf. Shilling 1978: 29, 31). Thus, according to Shilling (1978: 47), "one of the copula environments, that before +NP complement, has surface copula in non-past positive contexts in the vast majority of cases." Interestingly, am appears to be absent more frequently than is (cf. Reaser & Torbert 2004: 393).
