Bishop departing dance in swanky motor (4)
I believe the answer is:
limo
'swanky motor' is the definition.
'limo' can be an answer for 'motor' (I have seen 'Long motor' mean 'limo' so perhaps 'motor' could also mean 'limo'). I'm unsure of the 'swanky' bit.
'bishop departing dance' is the wordplay.
'bishop' becomes 'B' (abbreviation for bishop in chess).
'departing' suggests deleting specific letters.
'dance' becomes 'limbo' (type of dance).
'limbo' with 'b' removed is 'LIMO'.
'in' is the link.
Can you help me to learn more?
(Other definitions for limo that I've seen before include "Stretched car, often used for partying" , "Luxury car" , "Long motor" , "vehicle" , "Luxurious car (colloq.)" .)
