What Does “Increase” Mean?

Increase works as both a verb and a noun:

  • Verb: to become or make greater in size, amount, number, or intensity. Example: “Sales increased by 20 percent last quarter.”
  • Noun: a rise in size, amount, or level. Example: “There was a sharp increase in visitors this summer.”

It is one of the most general growth words in English. That generality is its weakness — “increase” never tells you whether something rose slightly or doubled, quickly or over years, in size or in strength. A good synonym answers those questions for you.

The Closest Alternatives to “Increase”

Grammar and Sentence Structure

“Increase” is flexible, and most of its synonyms follow the same patterns:

  • Transitive (you increase something): “They increased production.” Synonyms like raise, boost, expand, and enhance work the same way — “They boosted production.”
  • Intransitive (something increases on its own): “Prices increased.” Grow, escalate, multiply, and intensify also work without an object — “Prices escalated.”
  • As a noun: “an increase in demand” becomes “a boost in demand,” “a rise in demand,” or “an expansion of demand.”
  • Common prepositions: increase in (an increase in sales), increase by (increased by 10 percent), increase to (increased to one million). Most synonyms keep the same prepositions: “raised by 10 percent,” “grew to one million.”

Watch out: “enhance” and “amplify” need an object — you cannot say “sales enhanced.” And “escalate” usually needs a negative or neutral subject; “happiness escalated” sounds wrong. For a broader vocabulary upgrade, browse our synonyms for 200 common words for more everyday replacements.

When Not to Use a Synonym for “Increase”

Mistake 1: Using “escalate” for something positive.
Wrong: “Her happiness escalated after the good news.”
Correct: “Her happiness grew after the good news.”
Why: “Escalate” suggests a problem getting worse, so it clashes with positive feelings.

Mistake 2: Using “enhance” when you only mean “more.”
Wrong: “They enhanced the number of staff.”
Correct: “They increased the number of staff.”
Why: “Enhance” means to improve quality, not to raise a count.

Mistake 3: Using “multiply” for a small rise.
Wrong: “Prices multiplied by five percent.”
Correct: “Prices rose by five percent.”
Why: “Multiply” means to grow many times over — a five percent rise is far too small for it.
