A salad green diminished spread? (5)
I believe the answer is:
acres
'spread?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'a salad green diminished' is the wordplay.
'salad green' becomes 'cress' (cress is a kind of salad green).
'diminished' means to remove the last letter.
'cress' with its final letter taken off is 'cres'.
'a'+'cres'='ACRES'
Can you help me to learn more?
(Other definitions for acres that I've seen before include "Rival played" , "lots" , "farmland maybe?" , "Extensive landed property (often rolling)" , "Cares about these measurements?" .)
