Locate a hint (5)

I believe the answer is:

trace

I believe this clue is a double definition.

'locate' is the first definition.
(thesaurus)

'a hint' is the second definition.
('trace' can be a synonym of 'hint')

(Other definitions for trace that I've seen before include "Cater (anag.)" , "Follow step by step" , "Outline" , "Barely detectable amount" , "Tinge; copy" .)

I've seen this clue in The Times.
