Wee dollop (3)
I believe the answer is:
dab
'wee dollop' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dab that I've seen before include "Fingerprint - fish" , "Bad sort of small fish" , "Digital radio" , "Apply light touches of colour to the fish" , "Lightly press" .)
