Standard machine for racing? (5,3)
I believe the answer is:
stock car
'racing?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'standard machine' is the wordplay.
'standard' becomes 'stock' (synonyms).
'machine' becomes 'car' (synonyms).
'stock'+'car'='STOCK-CAR'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for stock car that I've seen before include "Type of racing" , "Modified motor for racing and ramming" , "production saloon" , "Vehicle adapted for bumping races" , "Production-line vehicle modified for racing" .)
