What does heighten mean?
“Heighten” means to make something stronger, more intense, more noticeable, or more significant. It is especially useful when discussing feelings, awareness, tension, interest, suspense, or the effect of an event or artistic choice. A sudden pause can heighten tension, while a public-information campaign can heighten awareness of a social or environmental issue. The word is common in formal writing but also occurs naturally in journalism, education, criticism, and everyday speech. Although it is related etymologically to “height,” its usual modern meaning concerns degree and intensity rather than physical measurement. “Heighten” is typically used with a direct object and is often more specific than the broad verb “increase,” suggesting that something is being made more pronounced or impactful. It can also carry a slightly elevated tone, especially when describing awareness, concerns, or dramatic effects.
