Make adjustment for a holiday out East (5)
I believe the answer is:
reset
'make adjustment' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'holiday out east' is the wordplay.
'holiday' becomes 'rest' (rest can mean a holiday or break).
'out' means one lot of letters goes inside another.
'east' becomes 'e' (abbreviation).
'rest' placed around 'e' is 'RESET'.
'for a' is the link.
Can you help me to learn more?
(Other definitions for reset that I've seen before include "Turn back to zero" , "Restore to required state" , "Replace, resettle or put back again" , "Restore to the initial readings" , "do this to make adjustment" .)
