One vehicle, among others, as used by travellers (8)
I believe the answer is:
caravans
'travellers' is the definition.
(I've seen this before)
'one vehicle among others as' is the wordplay.
'one vehicle' becomes 'van' (type of vehicle).
'among' means one lot of letters goes inside another (inserted letters are placed among others).
'others' becomes 'car' (I can't explain this - if you can you should believe this answer much more).
'car'+'as'='caras'
'van' going into 'caras' is 'CARAVANS'.
'used by' is the link.
Can you help me to learn more?
(Other definitions for caravans that I've seen before include "Campers equipped with living quarters" , "Processions of camels travelling together in single file" , "Mobile homes towed by cars" , "Vehicles with living quarters" , "Groups travelling together across deserts" .)
