The step most authors miss

Doing CRediT right? Don’t stop at the statement.

A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.

Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.

How hyperbole works

Hyperbole deliberately overstates something to a degree no one is expected to believe, which is precisely how it communicates intensity. "I am starving" rarely means literal starvation; it signals strong hunger. Because the exaggeration is recognisably untrue, it conveys emotion, humour or emphasis without deceiving anyone. Hyperbole appeals strongly to feeling, making it a natural partner of pathos. It is one of the most common figures in everyday speech, advertising and comedy, where overstatement is used to grab attention and dramatise a point.

Hyperbole and understatement

The opposite of hyperbole is understatement, which deliberately makes something seem less important than it is, as in describing a serious wound as "just a scratch". A specific form of understatement, litotes, affirms something by negating its opposite ("not bad at all" for "very good"). Where hyperbole amplifies, understatement minimises; both depart from literal accuracy for effect. Writers choose between them to control tone: hyperbole heightens drama or comedy, while understatement can convey irony, modesty or restraint.

Why writers use hyperbole

Hyperbole creates emphasis, emotion and humour. By stretching the truth, a writer can dramatise feelings ("my heart is broken into a thousand pieces"), exaggerate for comic effect, or make a persuasive point memorable. Advertising relies on it heavily, promising the "best" or "biggest" of everything. In literature, hyperbole intensifies a speaker’s state of mind and can reveal character through how extravagantly they speak. Because it works only when recognised as exaggeration, hyperbole loses its force if a reader mistakes it for a literal claim.

Common misconceptions

What people often get wrong

Often heard: Hyperbole is the same as lying.

Actually: Hyperbole is obvious, recognisable exaggeration used for effect, not deception. When someone says "this bag weighs a ton", no one is misled; both speaker and listener understand it as emphasis, which distinguishes it from a genuine lie.

Often heard: Hyperbole and understatement are similar devices.

Actually: They are opposites. Hyperbole exaggerates to make something seem greater, while understatement minimises to make something seem smaller or less important. Both depart from literal truth, but in opposite directions.

Often heard: Hyperbole only appears in casual conversation.

Actually: Although common in everyday speech, hyperbole is a long-established literary device used in poetry, drama and rhetoric to heighten emotion, create humour and make persuasive points memorable.
