Payment for one episode of a serial (10)
I believe the answer is:
instalment
'payment' is the definition.
(I've seen this before)
'one episode of a serial' 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.
'a' is found in the answer.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for instalment that I've seen before include "part of serial" , "Payment of part of debt" , "episode" , "Chapter" , "One of a series of partial payments" .)
