Vehicle on a road made of glass, possibly (7)
I believe the answer is:
tankard
'glass possibly' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'vehicle on a road' is the wordplay.
'vehicle' becomes 'tank' (tank is a kind of vehicle).
'on' says to put letters next to each other.
'road' becomes 'rd' (abbreviation).
'tank'+'a'+'rd'='TANKARD'
'made of' acts as a link.
Can you help me to learn more?
(Other definitions for tankard that I've seen before include "Drank at (anag)" , "Mug-like drinking vessel" , "One-handled drinking mug" , "Metal beer mug" , "Large drinking vessel" .)
