One girl to argue with another (6)
I believe the answer is:
rowena
'with another' is the definition.
I can't tell whether this definition defines the answer.
'one girl to argue' is the wordplay.
'one girl' becomes 'ena' (woman's name).
'to' means one lot of letters go next to another (I've seen this in other clues).
'argue' becomes 'row' (to row with someone is to argue with them).
'ena' after 'row' is 'ROWENA'.
Can you help me to learn more?
(Another definition for rowena that I've seen is " girl".)
