Copper with Bond finding lovely girl (5)
I believe the answer is:
cutie
'lovely girl' is the definition.
The definition suggests a singular noun which matches the answer.
'copper with bond' is the wordplay.
'copper' becomes 'cu' (chemical symbol).
'with' means one lot of letters go next to another.
'bond' becomes 'tie' (both can mean a connection).
'cu'+'tie'='CUTIE'
'finding' acts as a link.
Can you help me to learn more?
(Other definitions for cutie that I've seen before include "lovely" , "something pleasing" , "beauty" , "Smasher" , "Dish" .)
