Girl in school stuck with another (7)

I believe the answer is:

cohered

'stuck with another' is the definition.
(to cohere is to join or merge)

'girl in school' is the wordplay.
'girl' becomes 'her' ('her' refers to a girl or woman).
'in' is an insertion indicator.
'school' becomes 'coed' (a co-educational school).
'her' put within 'coed' is 'COHERED'.

I've seen this clue in The Times.
