Insect removed from control to become very angry (3,3,3,6)
I believe the answer is:
fly off the handle
'become very angry' is the definition.
'insect removed from control' is the wordplay.
I cannot really understand how this works, but
'insect' could be 'fly' (fly is a kind of insect) and 'fly' is present in the answer.
'removed' could be 'off' (as in an item of clothing taken off) and 'off' is found within the answer.
'control' could be 'handle' (handling is a kind of controlling) and 'handle' is present in the answer.
The remaining letters 'the' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'to' acts as a link.
Can you help me to learn more?
(Other definitions for fly off the handle that I've seen before include "react angrily" , "Robin perching on spade may" , "See red" , "Lose one's temper" .)
