Smoke from motor keeps inching around the edges (5)
I believe the answer is:
cigar
'smoke' is the definition.
(I've seen this before)
'motor keeps inching around the edges' is the wordplay.
'motor' becomes 'car' (I've seen this before).
'keeps' indicates putting letters inside.
'around the edges' means to remove the middle letters.
'inching' with its middle removed is 'ig'.
'car' going around 'ig' is 'CIGAR'.
'from' is the link.
(Other definitions for cigar that I've seen before include "Smoked item" , "Eg, Havana, panatella" , "Something to smoke" , "Havana, for example" , "Item kept in a humidor" .)
