In Scotland, it may suit the rest of the children (3)
I believe the answer is:
cot
'it may suit the rest of the children' is the definition.
The definition suggests a singular noun which matches the answer.
'in scotland' is the wordplay.
'in' says the answer is hidden in the clue.
'COT' is hidden within 'scotland'.
Can you help me to learn more?
(Other definitions for cot that I've seen before include "Camp bed" , "baby carrier?" , "Crib" , "Small child's bed" , "Baby's bed" .)
