One directs dude inebriated in posh car (6)
I believe the answer is:
rudder
'one directs' is the definition.
I can't judge whether this defines the answer.
'dude inebriated in posh car' is the wordplay.
'inebriated' indicates anagramming the letters (inebriated can mean drunk, suggesting disorder).
'in' is an insertion indicator.
'posh car' becomes 'rr' (short for Rolls Royce).
'dude' is an anagram of 'udde'.
'udde' put inside 'rr' is 'RUDDER'.
Can you help me to learn more?
(Other definitions for rudder that I've seen before include "Vessel steerer" , "It is used to steer a ship" , "Moving part of plane's tail" , "Ship's steering apparatus" , "Steering mechanism for a boat" .)
