Study by one of those in The House (4)
I believe the answer is:
room
'house' is the definition.
(thesaurus)
'study by one of those' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
The remaining letters 'rom' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'in the' is the link.
Can you help me to learn more?
(Other definitions for room that I've seen before include "Opportunity, scope" , "See 1" , "basic accommodation" , "Enclosed indoor space" , "kitchen?" .)
