Girl's name for a man and a boy? (6)
I believe the answer is:
alison
'girl's name' is the definition.
(I've seen this before)
'man and a boy?' is the wordplay.
'man' becomes 'ali' ().
'and' is a charade indicator (letters next to each other).
'a boy?' becomes 'son' ('son' can be a synonym of 'boy').
'ali'+'son'='ALISON'
'for a' acts as a link.
(Other definitions for alison that I've seen before include "lady" , "Girl's name" , "Girl" , "female" , "woman" .)
