Article on companies making drink (5)
I believe the answer is:
cocoa
'drink' is the definition.
(I know that cocoa is a type of drink)
'article on companies' is the wordplay.
'article' becomes 'a' (the indefinite article in English).
'on' says to put letters next to each other.
'companies' becomes 'coco' (co for company, twice).
'a' after 'coco' is 'COCOA'.
'making' is the link.
(Other definitions for cocoa that I've seen before include "Nighttime drink" , "Kind of chocolate drink" , "Main constituent of chocolate" , "product of beans!" , "Hot chocolate drink" .)
