In a variety that would probably be considered as acrolectal creole, it is quite usual to find a copula:
Jak sé an doktè.
[Jack COP INDF doctor]
'Jak is a doctor.'
There also exists a different structure with a focus on the noun, as in:
Sé doktè i yé.
[COP doctor 3SG be]
'He (really) is a doctor (...not a singer).'
