Heighten → It is formed from "high" (from Old English "hēah", meaning tall or elevated) and "-en" (a suffix used to form verbs indicating to make or become). The word "heighten" means to make something higher or to increase its elevation.
Think of something becoming 'tall' ('high') — the '-en' means to make it so. This helps you remember that 'heighten' means to make something higher.
