Common name - name of a girl, we hear (7)
I believe the answer is:
moniker
'common name' is the definition.
(I've seen this before)
'name of a girl we hear' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
'girl' could be 'nike' and 'nike' is located in the answer.
The remaining letters 'mr' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for moniker that I've seen before include "common name" , "Handle" , "Nickname" .)
