I aim to get round her (4)
I believe the answer is:
enid
'her' is the definition.
'i aim to get round' is the wordplay.
'aim' becomes 'end' (both can mean a goal or purpose).
'to get round' means one lot of letters goes inside another.
'i' placed within 'end' is 'ENID'.
(Other definitions for enid that I've seen before include "Geraint's wife's" , "W - - Blyton" , "Geraint's loved one" , "Lady" , "Dine with this girl" .)
