Reason a sommelier may visit Japan’s desert (7)
I believe the answer is:
forsake
'desert' is the definition.
(synonyms)
'reason a sommelier may visit japan's' is the wordplay.
I cannot really understand how this works, but
'reason' could be 'sake' (I've seen this in another clue) and 'sake' is present in the answer.
The remaining letters 'for' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for forsake that I've seen before include "'Abandon, desert (7)'" , "Give up" , "Abondon or renounce" , "Leave in the lurch" .)
