Depart for short rest in temporary accommodation (7)
I believe the answer is:
digress
'depart' is the definition.
(I know that depart can be written as digress)
'short rest in temporary accommodation' is the wordplay.
'short' means to remove the last letter.
'in' means one lot of letters goes inside another.
'temporary accommodation' becomes 'digs' (student accommodation. I am not sure about the 'temporary' bit.).
'rest' with its final letter taken off is 'res'.
'res' put into 'digs' is 'DIGRESS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for digress that I've seen before include "Stray from main subject" , "Ramble" , "Wander from one's path" , "Depart from the main subject" , "Wander from the point" .)
