Some land where a salad plant is cropped (5)
I believe the answer is:
acres
This clue could be a double definition.
'some land' is the first definition.
(acres measure land)
'where a salad plant is cropped' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
Can you help me to learn more?
(Other definitions for acres that I've seen before include "The Phoenix Park has 40 of them (5)" , "Land area measures" , "lots" , "Cares about these measurements?" , "large area of land" .)
