Rod appears repeatedly with a girl (7)
I believe the answer is:
barbara
'girl' is the definition.
'rod appears repeatedly with a' is the wordplay.
'rod' becomes 'bar' (I've seen this before).
'appears repeatedly' becomes 'bar' (I can't explain this - if you can you should believe this answer much more).
'with' says to put letters next to each other.
'bar'+'bar'+'a'='BARBARA'
Can you help me to learn more?
(Other definitions for barbara that I've seen before include "-- Hepworth, sculptor" , "- Hepworth, twentieth century English sculptress" , "girl" , "major title role for actress" , "Dame - Cartland, English author" .)
