Supporting vineyards, woman who’s operating the presses? (7)
I believe the answer is:
crusher
'who's operating the presses?' is the definition.
I can't judge whether this defines the answer.
'supporting vineyards woman' is the wordplay.
'supporting' means one lot of letters go next to another (in a down clue, some letters go under others).
'vineyards' becomes 'crus' (cru is a French term for a vineyard).
'woman' becomes 'her' (her refers to a woman).
'crus' put next to 'her' is 'CRUSHER'.
Can you help me to learn more?
(Another definition for crusher that I've seen is " Mill".)
