Root Explanation

Weaken is formed from "weak" (from Old English "wac", meaning not strong) and "-en" (a suffix used to form verbs indicating to make or become). The word "weaken" means to make something less strong or to become less strong.

Memory Tip

Think of something becoming 'not strong' ('weak') and the '-en' meaning to make it so. This helps you remember that 'weaken' means to make something less strong.
