Can, for example, turn up hint (5)
I believe the answer is:
tinge
'hint' is the definition.
(I've seen this before)
'can for example turn up' is the wordplay.
'can' becomes 'tin' ('tin' can be a synonym of 'can').
'for example' becomes 'eg' ('e.g.' can be a synonym of 'for example').
'turn up' is a reversal indicator.
'eg' backwards is 'ge'.
'tin'+'ge'='TINGE'
(Other definitions for tinge that I've seen before include "Slight but perceptible amount" , "Touch (of colour?)" , "Hint of colour" , "A colourful" , "A shade or a nuance" .)
