Copula occurrence is variable with predicative locative phrases. In general, the form of choice is is, with am and are seldom appearing. Shilling (1978: 59) indicates, however, that "more important in +LOC environment than the few examples of is are substantial numbers of sentences with de, be, does ... be, and, in the past, bin." De, however, is exclusively basilectal and occurs mostly on the so-called Out Islands rather than in Nassau (cf. Shilling 1978: 60); even in the basilect, however, its frequency is low, and speakers "far more frequently have zero + LOC". For other conditioning factors, cf. Feature 74 "Predicative adjectives".
