Ecstasy in freight vehicles (9)
I believe the answer is:
transport
This clue might be a double definition.
'ecstasy' is the first definition.
(I know that ecstasy can be written as transport)
'freight vehicles' is the second definition.
'transport' can be an answer for 'freight' (thesaurus). I'm not sure about the 'vehicles' bit.
'in' is the link.
Can you help me to learn more?
(Other definitions for transport that I've seen before include "Carriage" , "Delight; e.g. bus" , "Bear" , "Convict previously shipped" , "Move something or someone over a distance" .)
