Play on words - dig individual language! (7)
I believe the answer is:
punjabi
'language' is the definition.
(Punjabi is an example)
'play on words dig individual' is the wordplay.
'play on words' becomes 'pun' ('pun' can be a synonym of 'play on words').
'dig' becomes 'jab' ('jab' can be a synonym of 'dig').
'individual' becomes 'i'.
'pun'+'jab'+'i'='PUNJABI'
(Other definitions for punjabi that I've seen before include "Indian language" , "Language spoken in an area between Pakistan and India" , "Possibly Pakistani" , "Subcontinental language" , "tongue" .)
