Short school period to accommodate every one individually — so I work less? (7)
I believe the answer is:
teacher
'one individually so i work less?' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'short school period to accommodate every' is the wordplay.
'short' means to remove the last letter.
'school period' becomes 'term' (I've seen this before).
'to accommodate' means one lot of letters goes inside another.
'every' becomes 'each' (synonyms).
'term' with its last letter taken off is 'ter'.
'ter' enclosing 'each' is 'TEACHER'.
(Other definitions for teacher that I've seen before include "Pedagogue" , "School educator" , "supply?" , "Mentor" , "Lecturer" .)
