Nice way to support nut production? Wrong (6)
I believe the answer is:
untrue
'wrong' is the definition.
(synonyms)
'nice way to support nut production?' is the wordplay.
'nice way' becomes 'rue' (I've seen this before).
'to support' means one lot of letters go next to another (in a down clue, some letters hold up others).
'production?' is an anagram indicator (I've seen 'production' mean this).
'nut' with letters rearranged gives 'unt'.
'rue' after 'unt' is 'UNTRUE'.
(Other definitions for untrue that I've seen before include "Not loyal" , "Wrong" , "Incorrect or false" , "Not factual or honest" , "Not accurate or veracious" .)
