He may be on time for the match (6)
I believe the answer is:
keeper
This clue could be a double definition.
'he may be on time' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'match' is the second definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'for the' is the link.
Can you help me to learn more?
(Other definitions for keeper that I've seen before include "slips on my right hand usually" , "stockist" , "Custodian, steward" , "One looks after something, museum or game perhaps" , "Zoo or park manager" .)
