He may reorganise the classroom, aptly enough (12)
I believe the answer is:
schoolmaster
'he' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'reorganise the classroom aptly enough' is the wordplay.
'the classroom' can be anagrammed to 'SCHOOLMASTER'.
But, I'm not sure how this is indicated.
'may' is the link.
Can you help me to learn more?
(Other definitions for schoolmaster that I've seen before include "Male teacher" , "The classroom (anag)" , "One teaching" .)
