Where the gardener's children were raised? (7)
I believe the answer is:
nursery
'where the gardener's children were raised?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for nursery that I've seen before include "Scene of young children or plants" , "Such cannons repeatedly taken" , "place for cultivation" , "cannon" , "sort of rhyme" .)
