What the birds do when he teases them? (7)
I believe the answer is:
'what the birds do when he teases them?' is the definition.
The definition suggests a singular noun which matches the answer.
'what the birds do when he' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is found in the answer.
'he' could be 'wit' and 'wit' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
