Fine writer gets most of the royalty (7)
I believe the answer is:
penalty
'fine' is the definition.
(I've seen this in another clue)
'writer gets most of the royalty' is the wordplay.
I cannot quite see how this works, but
'writer' could be 'pen' (something which writes) and 'pen' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
The remaining letters 'aly' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for penalty that I've seen before include "Punishment; fine" , "Punishment eg for foul" , "Fine - handicap" , "Spot kick" , "Perhaps fine" .)
