A little notice (4)
I believe the answer is:
spot
This clue is a double definition.
'a little' is the first definition.
(thesaurus)
'notice' is the second definition.
(thesaurus)
(Other definitions for spot that I've seen before include "Catch sight of mark in pots" , "Catch sight of - pimple" , "Lady Macbeth: ''Out, damned . . . .!''" , "Identify" , "Dirty blemish" .)
