editorials

I'm a little stuck... Click here to teach me more about this clue!

'articles' is the definition.
(editorial is a kind of article)

I don't understand the remainder of the clue.

(Other definitions for editorials that I've seen before include "Leading articles" , "Leaders" , "Newspapers' opinion columns" .)

I've seen this clue in The Irish Times.
