She has medals mixed up (6)
I believe the answer is:
damsel
'she' is the definition.
(a damsel is a young woman)
'medals mixed up' is the wordplay.
'mixed up' indicates an anagram.
'medals' is an anagram of 'DAMSEL'.
'has' acts as a link.
(Other definitions for damsel that I've seen before include "Girl (literary)" , "distressed girl?" , "Someone in distress?" , "Old-fashioned young woman" , "Young single woman" .)
