He's cut short, so there's some silence (3)
I believe the answer is:
len
'he's cut short so' is the definition.
I know nothing about this answer so I can't tell whether this works.
'some silence' is the wordplay.
'some' means to look at the middle letters.
The central letters of 'silence' are 'LEN''.
'there's' is the link.
Can you help me to learn more?
(Other definitions for len that I've seen before include "Boy" , "Sir - - Hutton" , "- - Hutton, cricketer" , "-- Deighton, author" , "Leonard (dim.)" .)
