Root Explanation

Retrofit is formed from "retro-" (meaning backward) and "fit" (from Old English "fittan", meaning to make or to put). The word describes the act of fitting or adding new technology or features to something that is older or existing, essentially making it better or more modern by going backward to improve.

Memory Tip

Think of 'retro' meaning backward, and 'fit' meaning to make or put. This helps you remember that retrofit means to make something older better by adding new features.
