Mates Scott and Gerald divided by the sound of it (4)
I believe the answer is:
fits
'mates scott and gerald divided' is the definition.
I can't judge whether this definition defines the answer.
'by the sound of it' is the wordplay.
'by' is a charade indicator (letters next to each other).
'the sound' becomes 'fit' (I've seen this in another clue).
'of it' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'fit' put next to 's' is 'FITS'.
Can you help me to learn more?
(Other definitions for fits that I've seen before include "Is of the right shape and size" , "Seizures" , "Prepares" , "short bouts" , "feels comfortable" .)
