Talk foolishly, claiming I'm human perhaps? (7)
I believe the answer is:
primate
'human perhaps?' is the definition.
(human is a kind of primate)
'talk foolishly claiming i'm' is the wordplay.
'talk foolishly' becomes 'prate' (I've seen this before).
'claiming' indicates putting letters inside.
'prate' enclosing 'im' is 'PRIMATE'.
(Other definitions for primate that I've seen before include "Highest-ranking bishop" , "bishop, perhaps" , "Ape or churchman" , "Archbishop of York, for example" , "Man (or monkey)" .)
