The characteristic spirit and values of a person, culture or institution. In Aristotle's Rhetoric it is narrower and sharper: persuasion achieved through the character the speaker projects in the course of speaking — not through their credentials.
No single coiner — an ordinary Greek noun given technical use by Aristotle.
// Where it sits
Aristotle's version is entirely the second. That's what makes it teachable.
What it really means
Every school explanation of ethos says it means credibility — your qualifications, your track record, the reason the audience should trust you before you open your mouth.
Aristotle explicitly rules that out, in the sentence immediately after defining it: this confidence must be due to the speech itself, not to any preconceived idea of the speaker's character.
Which changes everything about what the term is for. Reputation walks in the door with you and can't be taught. Ethos has to be manufactured on stage, inside this particular speech, out of the choices you make in it — which is precisely why Aristotle counts it as one of the technical means of persuasion. It's an art. An unknown speaker can build enormous ethos in three minutes; a famous one can destroy theirs in a paragraph.
The Greek supports the reading. ἦθος — settled character — is intimately tied to ἔθος, habit. Character is sedimented custom: what you've repeatedly done, showing. And in a speech, what you've repeatedly done is every sentence so far.
One correction on the famous trio. Ethos, pathos and logos are usually presented as three co-equal pillars, sometimes with kairos bolted on as a fourth. Aristotle names three, not four, and doesn't treat them as equals — logos and the enthymeme are the methodical core. He also calls ethos almost the most effective means of proof, which pulls against that. The tidy tripod is a teaching aid that flattens a real tension in the text.
Where it comes from
The long-vowel form means character as formed by the short-vowel form, habit — character is sedimented custom. English 'ethics' comes from the same pair.
Myths & misconceptions
Ethos is your credentials — your reputation, title or track record.
Aristotle rules this out in the very next sentence after defining it: 'this confidence must be due to the speech itself, not to any preconceived idea of the speaker's character.' Credentials are exactly what ethos is not; it has to be built inside the speech.
Ethos, pathos and logos are three co-equal pillars, with kairos as a fourth.
They're three technical means of persuasion, and Aristotle does not treat them as equals — though the text pulls both ways: Book I chapter 1 calls the enthymeme the substance of rhetorical persuasion, while chapter 2 calls character almost the most effective means of proof. Kairos doesn't appear as a fourth mode at all; he consistently affirms only three.
Compare & contrast
Ethos vs reputation
Reputation walks in the door with you; ethos has to be manufactured on stage. Aristotle's whole point is that the second is an art and the first isn't — which is why an unknown speaker can have enormous ethos and a famous one can squander theirs in a paragraph.

Questions people ask
- What is ethos in rhetoric?
- Persuasion through the speaker's character — but character as displayed in the speech, not as known beforehand. Aristotle at Rhetoric 1.2.4: this confidence must be due to the speech itself, not to any preconceived idea of the speaker's character.
- Is kairos the fourth rhetorical appeal?
- Not in Aristotle. The Rhetoric affirms only three technical means of persuasion and makes no mention of kairos as a fourth. Kairos is a Sophistic concept that later teaching traditions attached to Aristotle's three.
- Which is most important — ethos, pathos or logos?
- Aristotle calls ethos, 'so to say', 'the most effective means of proof' at 1.2.4, yet the Rhetoric overall privileges logos, since people are most easily persuaded when they suppose something to have been proven. The text pulls both ways — the tidy tripod flattens a real tension in the work.
