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