One trying to get a half of beer after the match? (6)
I believe the answer is:
tester
'one trying to' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'a half of beer after the match?' is the wordplay.
'a half of' means to take half the letters.
'after' is a charade indicator (letters next to each other).
'the match?' becomes 'test' (as in a test match in cricket).
'beer' halved is 'er'.
'er' put after 'test' is 'TESTER'.
'get' is the link.
Can you help me to learn more?
(Other definitions for tester that I've seen before include "covering at night" , "Difficult question or challenge" , "One pumps" , "Old sixpence for a bed canopy" , "Trial sample; bed canopy" .)
