Don’t go and mention cuddling teddy at the front (4)
I believe the answer is:
stay
'don't go' is the definition.
(I've seen this before)
'mention cuddling teddy at the front' is the wordplay.
'mention' becomes 'say' (I can't explain this - if you can you should give a lot more credence to this answer).
'cuddling' is an insertion indicator.
'at the front' says to take the initial letters.
The first letter of 'teddy' is 't'.
'say' placed around 't' is 'STAY'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for stay that I've seen before include "Reside" , "Rope or wire used to support a mast" , "Support, delay" , "guy giving > support" , "Visit (for the night)" .)
