Soft and luxuriant pile fabric (5)
I believe the answer is:
plush
I believe this is a quadruple definition!!
'soft' is the first definition.
(thesaurus)
'and' acts as a link.
'luxuriant' is the second definition.
(I've seen this in another clue)
'pile' is the third definition.
(thesaurus)
'fabric' is the fourth definition.
(plush is a kind of fabric)
(Other definitions for plush that I've seen before include "Cut pile, softer than velvet" , "Fabric with a long velvety pile" , "Fabric; richly luxurious" , "Rich fabric" .)
