Ethos
Ethos is a Greek word meaning 'character'. In terms of persuasive language, it is an appeal to authority and credibility. Ethos is a means of convincing an audience of the reliable character or credibility of the speaker/writer, or the credibility of the argument. It is an important tool of persuasion because if you can get your audience to see you (or your argument) as credible and trustworthy, it will be much easier to persuade them. (ex: As a doctor, I can say that this product will certainly improve your health)
Logos
Logos is a Greek word meaning 'a word' or 'reason'. In rhetoric, it is an appeal to logic and reason. It is used to persuade an audience by logical thought, fact and rationality. Logos can be a useful tool of persuasion because if you can 'prove' an argument through logical and sound reasoning, your audience is more likely to be persuaded.
