After wordplay, poke one's tongue? (7)
I believe the answer is:
'tongue?' is the definition.
(Punjabi is an example)
'after wordplay poke one's' is the wordplay.
'after' is a charade indicator (letters next to each other).
'wordplay' becomes 'pun' (synonyms).
'poke' becomes 'jab' (jab is a kind of poke).
'one' becomes 'i' (Roman numeral).
'pun'+'jab' is 'punjab'.
(Other definitions for punjabi that I've seen before include "talk of Amritsar?" , "tongue" , "Language spoken in an area between Pakistan and India" , "Subcontinental language" , "From a state in Northwest India" .)
