The elite, in fact, ride all over the place (8,7)
I believe the answer is:
definite article
'the' is the definition.
'elite in fact ride all over the place' is the wordplay.
'all over the place' indicates an anagram.
'elite'+'in'+'fact'+'ride'='eliteinfactride'
'eliteinfactride' anagrammed gives 'DEFINITE ARTICLE'.
(Other definitions for definite article that I've seen before include "Maybe the" , "Black and white feature in paper" , "In English, it's always the" , "part of speech" .)
