Cream from Aldi, regularly described by French and English (5)
I believe the answer is:
elite
'cream' is the definition.
(as in the cream of the crop)
'aldi regularly described by french and english' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'described by' means one lot of letters goes inside another (to describe can mean to form an outline).
'french and' becomes 'et' ('and' in French).
'english' becomes 'E' (abbreviation).
The alternate letters of 'aldi' are 'li'.
'li' inserted into 'et' is 'elit'.
'elit'+'e'='ELITE'
'from' acts as a link.
(Other definitions for elite that I've seen before include "12 letters = 1 inch (type)" , "Exclusive group" , "Chosen ones" , "Select body, cream" , "Best, privileged, group" .)
