The Adverb of Real: Really

Adverbs 2 min read Updated 24 August 2026

The adverb of real is really.

How really is formed

The adjective ends in l, so adding -ly gives two: real + ly = really.

Identical in form to cool → coolly and cruel → cruelly. What makes really unusual is not the spelling but the meaning, which has drifted a long way from real.

Really in a sentence

Is that really what he said? Expressing doubt or surprise, the most frequent use.
The film was really good. Simply an intensifier meaning very.
He really believed it. The original sense: genuinely, in fact.

Where it is actually used

really good / bad / interesting As a plain intensifier, meaning very.
not really A softened refusal, one of the most common phrases in spoken English.
Really? On its own, expressing surprise or scepticism.

Really or something else?

Several adverbs sit close to really, and the difference between them is usually meaning rather than formality.

very Only intensifies. It cannot mean in fact. Did he very mean it? is impossible.
truly Formal, and about sincerity rather than emphasis.
actually Signals a correction. He actually believed it implies you expected otherwise.

A note on overuse

In formal writing, really as an intensifier is usually the first word an editor cuts. The results were really surprising is almost always stronger as the results were surprising. Keep it where it carries the original sense of in fact.

Frequently asked

Why does really so often just mean very?
Intensifiers wear down with use. Really began as in reality, and constant use as emphasis gradually bleached the original meaning. Very itself took the same path, from Old French verai, meaning true.
