After a round we have something to pay (3)
I believe the answer is:
owe
'something to pay' is the definition.
I can't judge whether this definition defines the answer.
'after a round we' is the wordplay.
'after' says to put letters next to each other.
'a round' becomes 'o' (round can mean a round object).
'o'+'we' is 'OWE'.
'have' acts as a link.
Can you help me to learn more?
(Other definitions for owe that I've seen before include "Be beholden" , "Have to thank" , "have favours to return" , "Have a debt to (someone)" , "Be indebted" .)
