One who should apologise getting into row during play? (9)
I believe the answer is:
latecomer
'one who should apologise getting into row during play?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'one' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'me' (a setter might use 'one' to humourously mean 'me') and 'me' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for latecomer that I've seen before include "Ace Merlot (anag)" , "Person arriving behind time" , "One arriving after time" , "Perhaps one held up" , "one's a poor timekeeper" .)
