Girl seen in Michigan or Maine (5)
I believe the answer is:
norma
'girl' is the definition.
'in michigan or maine' is the wordplay.
'in' says the answer is hidden in the clue.
'NORMA' is hidden within 'michigan or maine'.
'seen' acts as a link.
(Other definitions for norma that I've seen before include "Opera - ex-PM's wife" , "Shearer or Major" , "Bellini opera - girl's name" , "Roman (anag) - girl's name" , "Bellini drama" .)
