Twig, for example, brought back by bird (3,2)
I believe the answer is:
get it
'twig' is the definition.
(synonyms)
'example brought back by bird' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'brought back' shows that the letters should be reversed in order.
'by' is a charade indicator (letters next to each other).
'bird' becomes 'tit' (tit is a kind of bird).
'eg' in reverse letter order is 'ge'.
'ge'+'tit'='GET IT?'
'for' acts as a link.
(Other definitions for get it that I've seen before include "twig?" , "Be punished" , "Understand" , "See the point" .)
