Josh getting Sunday lunch for one (5)
I believe the answer is:
roast
'josh' is the definition.
(thesaurus)
'sunday lunch for one' is the wordplay.
I cannot really see how this works, but
'sunday' could be 's' and 's' is found in the answer.
'one' could be 'a' (a thing is one thing) and 'a' is found in the answer.
The remaining letters 'rot' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for roast that I've seen before include "Cook; criticise" , "Traditional Sunday lunch" , "Berate - cook" , "Get very warm" , "Tear to pieces" .)
