Article I had to back up (3)

Ross

I believe the answer is:

aid

'back up' is the definition.
(aiding is a kind of backing up)

'article i had' is the wordplay.
'article' becomes 'a' (English indefinite article).
'i had' becomes 'i'd' (I'd).
'a'+'id'='AID'

'to' is the link.

(Other definitions for aid that I've seen before include "assistant" , "Help or support" , "Good point" , "Help. Assist" , "A hand" .)

I've seen this clue in the Evening Standard.
