I believe the answer is:

imogen

I'm a little stuck... Click here to teach me more about this clue!

'is she' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for imogen that I've seen before include "Shakespearean heroine" , "Girl's name; go mine (anagram)" , "Woman" , "girl" , "Female character in Cymbeline" .)

I've seen this clue in the Evening Standard.
