Root Explanation

Backfit is formed from "back" (from Old English "bæc", meaning the rear or reverse side) and "fit" (from Old English "fittan", meaning to make suitable or to adjust). The word "backfit" refers to the process of making adjustments or modifications to something, often to bring it up to current standards or requirements.

Memory Tip

Think of making something suitable or adjusting it ('fit') for the rear or reverse side ('back') — that's what backfit means.
