Leather moved to and fro loudly (5)
I believe the answer is:
suede
'leather' is the definition.
(I know that suede is a type of leather)
'moved to and fro loudly' is the wordplay.
'moved to and fro' becomes 'swayed' (to sway is to move to and fro).
'loudly' indicates a 'sounds like' (homophone) clue (when spoken - not silently).
'swayed' is a homophone of 'SUEDE'.
(Other definitions for suede that I've seen before include "Soft leather with one side napped" , "Hide from kids" , "material used in gloves" , "Soft goatskin" , "Type of leather" .)
