Bolts with a girl (7)
I believe the answer is:
barbara
'bolts with a girl' is the definition.
I can't judge whether this defines the answer.
'bolts with a girl' is the wordplay.
'bolts with' becomes 'barb' (I can't justify this - if you can you should give a lot more credence to this answer).
'a girl' becomes 'Ara'.
'barb'+'ara'='BARBARA'
Can you help me to learn more?
(Other definitions for barbara that I've seen before include "female officer in SA" , "Major -, (G.B. Shaw)" , "Major --, play by Shaw" , "girl" , "Major -, (G. B. Shaw)" .)
