Support or assistance given to someone or something, often in the form of approval, endorsement, or financial help.

Backing → It is formed from "back" (from Old English "bæc", meaning the rear or support) and "-ing" (a suffix used to form nouns indicating an action or resulting state). The word "backing" refers to the act of providing support or assistance, particularly from behind.
Think of providing support from the 'rear' ('back') — that's what backing means.
