Scraps rum before crew starts to turn seditious (8)
I believe the answer is:
oddments
'scraps' is the definition.
('oddment' can be a synonym of 'scrap')
'rum before crew starts to turn seditious' is the wordplay.
'rum before' becomes 'odd' (I can't explain this - if you can you should believe this answer much more).
'crew' becomes 'men' (I've seen this before).
'starts to' indicates taking the first letters.
The first letters of 'turn seditious' is 'ts'.
'odd'+'men'+'ts'='ODDMENTS'
Can you help me to learn more?
(Other definitions for oddments that I've seen before include "Remnants" , "Bits and bobs" , "just a few items" , "Isolated articles, left-overs." , "Bits and pieces, isolated garments" .)
