Turn red with embarrassment (5)
I believe the answer is:
blush
'turn red with embarrassment' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for blush that I've seen before include "reddish tinge" , "Redden in shame or modesty" , "look embarrassed" , "Redden (in the face)" , "Pinkish type of wine" .)
