Chap taken in by one girl or another (6)
I believe the answer is:
amanda
'or another' is the definition.
I can't judge whether this definition defines the answer.
'chap taken in by one girl' is the wordplay.
'chap' becomes 'man' (chap can mean a man).
'taken in by' is an insertion indicator (back).
'one girl' becomes 'ada' (girl's name).
'man' placed within 'ada' is 'AMANDA'.
Can you help me to learn more?
(Other definitions for amanda that I've seen before include "Girl" , "F. name meaning lovable" , "Girl's name meaning lovable" .)
