She romps, but doesn't exactly toy with a lad (6)
I believe the answer is:
tomboy
'she romps but doesn't exactly' is the definition.
I can't tell whether this defines the answer.
'toy with a lad' is the wordplay.
'toy with' becomes 'tom' (I can't explain this - if you can you should believe this answer much more).
'a lad' becomes 'boy' (I've seen this in another clue).
'tom'+'boy'='TOMBOY'
Can you help me to learn more?
(Other definitions for tomboy that I've seen before include "Girl who likes rough and noisy activities" , "girl behaving boisterously" , "Wild, boisterous girl" , "Girl enjoying traditionally male activities" , "Girl enjoying rough outdoor activities" .)
