What a deviator may do to be of use out West? (6)
I believe the answer is:
swerve
'what a deviator may do' is the definition.
The definition suggests a singular noun which matches the answer.
'be of use out west?' is the wordplay.
'be of use' becomes 'serve' (I've seen this before).
'out' indicates putting letters inside.
'west?' becomes 'W' (abbreviation).
'serve' enclosing 'w' is 'SWERVE'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for swerve that I've seen before include "Turn aside from straight course to avoid something (6)" , "Veer wildly" , "Using spin" , "Turn suddenly aside from a straight course" , "Sharp turn" .)
