Insect found in currants (3)
I believe the answer is:
ant
'insect' is the definition.
(ant is a kind of insect)
'in currants' is the wordplay.
'in' indicates a hidden word.
'ANT' is hidden in the letters of 'currants'.
'found' acts as a link.
(Other definitions for ant that I've seen before include "Termite" , "Industrious insect" , "that may be a soldier" , "Six-footer" , "Emmet or pismire" .)
