Phoned about a girl, talking wildly (6)
I believe the answer is:
raving
'talking wildly' is the definition.
'raving' can be an answer for 'talking' (raving is a kind of talking). I'm not certain of the 'wildly' bit.
'phoned about a girl' is the wordplay.
'phoned' becomes 'rang' ('ring' can be a synonym of 'phone').
'about' means one lot of letters goes inside another.
'a girl' becomes 'Vi' (short for Violet).
'rang' enclosing 'vi' is 'RAVING'.
Can you help me to learn more?
(Other definitions for raving that I've seen before include "Declaiming wildly" , "Mad" , "Wildly incoherent" .)
