He may have to sit out, saying nothing (3)
I believe the answer is:
len
'he may have' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'sit out saying nothing' is the wordplay.
'out' is a deletion indicator.
'saying nothing' becomes 'silent' (saying nothing is being silent).
'silent' with 'sit' taken out is 'LEN''.
'to' is the link.
Can you help me to learn more?
(Other definitions for len that I've seen before include "- - Hutton, cricketer" , "Sir - - Hutton" , "Leonard (dim.)" , "Boy" , "-- Deighton, author" .)
