Kid had a swing we hear (5)
I believe the answer is:
suede
'kid' is the definition.
(both are types of leather)
'had a swing we hear' is the wordplay.
'had a swing' becomes 'swayed' (to sway is to swing around).
'we hear' shows a homophone (sound like).
'swayed' sounds like 'SUEDE'.
(Other definitions for suede that I've seen before include "Brushed leather" , "unprepared material" , "Kid possibly" , "Soft goatskin" , "Hide from kids" .)
