It's in Spanish article - first one favouring a select group (7)
I believe the answer is:
elitist
'one favouring a select group' is the definition.
(I've seen this before)
'it's in spanish article first' is the wordplay.
'in' indicates putting letters inside.
'spanish article' becomes 'el' (the definite article 'the' in Spanish).
'first' becomes 'ist' (ist resembles 1st).
'el'+'ist'='elist'
'it' inserted into 'elist' is 'ELITIST'.
(Other definitions for elitist that I've seen before include "One who treats certain people as superior group" , "Looking down on others" , "Member of a self-regarding group" , "One without the common touch" , "Favouring a chosen few" .)
