heighten
UK: ˈhaɪt(ə)n | US: ˈhaɪt(ə)n
vt. to make or become higher or more intense
vi. to increase in degree or intensity
The word "heighten" combines "height" (from Old English hēahþu, meaning "elevation" or "top") with the verb-forming suffix "-en" (from Old English -nian), which means "to cause to be." This suffix often transforms nouns or adjectives into verbs (e.g., "strengthen," "sharpen"). The logical progression reflects the action of raising something physically or metaphorically, such as increasing intensity or degree.
