Sailor in US city with small vehicle (6)
I believe the answer is:
lascar
'sailor' is the definition.
(I know that Lascar is a type of sailor)
'us city with small vehicle' is the wordplay.
'us city' becomes 'LA' (short for Los Angeles).
'with' says to put letters next to each other.
'small' becomes 's' (abbreviation - e.g. clothes size).
'vehicle' becomes 'car' (car is a kind of vehicle).
'la'+'s'+'car'='LASCAR'
'in' acts as a link.
(Other definitions for lascar that I've seen before include "Asian sailor" , "The East Indian sailor is a rascal" , "Eastern sailor" , "Rascal (anag) - oriental seaman" , "Camp-follower" .)
