Scrabble piece returned by first snob? (7)
I believe the answer is:
elitist
'snob?' is the definition.
(I've seen this before)
'scrabble piece returned by first' is the wordplay.
'scrabble piece' becomes 'tile' (Scrabble is played with tiles with letters on).
'returned' says the letters should be written backwards.
'by' says to put letters next to each other.
'first' becomes 'ist' (ist resembles 1st).
'tile' reversed gives 'elit'.
'elit'+'ist'='ELITIST'
(Other definitions for elitist that I've seen before include "Its tile (anag.)" , "Member of a self-regarding group" , "Believer in the superiority of a few" , "One who believes that certain people are superior" , "One showing superior attitude" .)
