American soldier going back in vehicle that produces smoke (5)
I believe the answer is:
cigar
'produces smoke' is the definition.
'cigar' can be an answer for 'smoke' (smoke can mean a cigar). I am unsure of the 'produces' bit.
'american soldier going back in vehicle' is the wordplay.
'american soldier' becomes 'GI' (informal term for a US soldier).
'going back' says the letters should be written in reverse.
'in' indicates putting letters inside.
'vehicle' becomes 'car' (car is a kind of vehicle).
'gi' back-to-front is 'ig'.
'ig' put within 'car' is 'CIGAR'.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for cigar that I've seen before include "Roll of cured tobacco" , "Item kept in a humidor" , "Havana, for example" , "Cylinder of tobacco" , "A roll of leaf tobacco" .)
