Reviewed by the Grammarlyzer Editorial Team · Our Review Standards · Published May 18, 2026 · Updated July 16, 2026

Separate the adjective from the noun, then choose among the noun's current senses.

Quick Answer

Enormous is an adjective for extraordinarily great size, number, or degree.

Enormity is a noun that can mean wickedness, immensity, or momentous importance or impact.

First test: If you need an adjective before a noun, use enormous. If you need a noun, decide whether enormity, size, or scale expresses the intended sense most clearly.

Key Takeaway

Write "an enormous cost" because the slot needs an adjective. "The enormity of the crime" uses the noun's wickedness or momentous-impact sense; "the scale of the project" is a neutral magnitude choice.

Use Enormous for Size

Enormous is the safe everyday choice when you are describing something as very large. It can describe physical size, cost, effort, influence, or number.

If the sentence is mainly about choosing a precise formal word, compare this rule with academic writing words. If the confusion comes from similar-looking vocabulary, review similar-sounding words next.

Correct:

The project required an enormous budget.

Budget is an amount, so the adjective enormous works.
Correct:

They faced an enormous challenge.

Challenge is being described as very large or difficult.

Use Enormity as a Noun

Enormity can point to an immoral act or great wickedness, but current dictionaries also record immensity and momentous importance. Because some readers resist the size sense, size or scale can be clearer when neutral magnitude is all you mean.

Correct:

Fraud carries moral seriousness, so enormity fits.
Correct:

The sentence focuses on serious consequences.
