The gardener can rake it fine (5)
I believe the answer is:
tilth
'fine' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for tilth that I've seen before include "Sort of soil" , "Arable land that is worked by ploughing and sowing" , "Ploughed land" , "sow here" , "Cultivate" .)
