I believe the answer is:

miranda

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

'woman' is the definition.

I can't explain the remainder of the clue.

(Other definitions for miranda that I've seen before include "Female comedian" , "Issue of Prospero's" , "Shakespearean heroine" , "Prospero's daughter (The?Tempest)" , "Prospero's daughter (Tempest)" .)

I've seen this clue in The Irish Times.
