Little room for scholastic endeavour (5)
I believe the answer is:
study
'little room' is the definition.
'study' can be an answer for 'room' (study is a kind of room). I am unsure of the 'little' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for study that I've seen before include "Scrutinize" , "Something worth observing" , "Den - learning" , "Revise" , "Learn; den" .)
