Work always covering term time for school inspectors? (4,3)
I believe the answer is:
open day
'school inspectors?' is the definition.
The definition suggests a singular noun which matches the answer.
'work always covering term time' is the wordplay.
'work' becomes 'op' (short for opus).
'always covering term' becomes 'en' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'time' becomes 'day' (day is a kind of time).
'op'+'en'+'day'='OPEN DAY'
'for' is the link.
Can you help me to learn more?
(Other definitions for open day that I've seen before include "Free access time" , "Dostoyevsky novel" , "possible to look freely round now" , "When public may visit, eg, school" , "Public visiting time" .)
