Articulated holiday vehicle's slower (5)
I believe the answer is:
brake
'slower' is the definition.
(I've seen this before)
'articulated holiday' is the wordplay.
'articulated' indicates a 'sounds like' (homophone) clue.
'holiday' becomes 'break' (break can mean a holiday or time off).
'break' sounds like 'BRAKE'.
'vehicle's' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for brake that I've seen before include "Device for slowing vehicle" , "Slower" , "Decelerate" , "Device to slow down a vehicle" , "Restraint on vehicle" .)
