Out of school holidays, engaging one caretaker (7)
I believe the answer is:
interim
'caretaker' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for interim that I've seen before include "Caretaker" , "Stopgap" , "acting" , "temporary period" , "Meantime - provisional" .)
