Grand, opulent, almost plush? (6)
I believe the answer is:
fabric
'plush?' is the definition.
(plush is a kind of fabric)
'grand opulent almost' is the wordplay.
'grand' becomes 'fab' (I can't justify this - if you can you should believe this answer much more).
'opulent' becomes 'rich' (similar in meaning).
'almost' means to remove the last letter (almost the whole word is kept).
'rich' with its final letter taken off is 'ric'.
'fab'+'ric'='FABRIC'
Can you help me to learn more?
(Other definitions for fabric that I've seen before include "Cotton or tweed, say" , "(Texture of) cloth" , "Material in general" , "Building structure; textile" , "Woven, knitted or felted cloth" .)
