Benefit of getting ahead in transport (5)
I believe the answer is:
bonus
'benefit of' is the definition.
The answer and definition can be both related to property as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'ahead in transport' is the wordplay.
'ahead' becomes 'on' (synonyms).
'in' indicates putting letters inside.
'transport' becomes 'bus' (bus is a kind of transport).
'on' placed inside 'bus' is 'BONUS'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for bonus that I've seen before include "Extra dividend" , "Additional payment to encourage productivity" , "Something more than you expected" , "Good performance reward" , "Additional payment for work, often on merit" .)
