Fleeces for gents and women switched (4)
I believe the answer is:
wool
'fleeces for' is the definition.
The definition suggests a singular noun which matches the answer.
'gents and women switched' is the wordplay.
'gents' becomes 'loo' (I can't justify this - if you can you should believe this answer much more).
'and' says to put letters next to each other.
'women' becomes 'w'.
'switched' says the letters should be written in reverse.
'loo'+'w'='loow'
'loow' back-to-front is 'WOOL'.
Can you help me to learn more?
(Other definitions for wool that I've seen before include "Yarn for knitting" , "Sheep's coat" , "Sheep's hair" , "Fabric from fleece" , "Hair of sheep etc" .)
