Thank second person when beginning to make exit (3-3)
I believe the answer is:
way-out
'exit' is the definition.
(I know that exit can be written as way out)
'thank second person when beginning' is the wordplay.
I cannot really understand how this works, but
'second person' could be 'you' (second person pronoun) and 'you' is found within the answer.
The remaining letters 'wat' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'to make' is the link.
Can you help me to learn more?
(Other definitions for way-out that I've seen before include "Extremely unconventional" , "John --, celebrated cricket commentator" , "Bizarre - exit" , "Exit - eccentric" , "Offbeat" .)
