Ethos is a type of persuasive writing or speaking that authors use to convince their audience of their point of view. It is based on the speaker or writer’s credibility, trustworthiness, and character. It's like if your mom tried to convince you to eat your vegetables by saying you should because she’s worked hard to make sure to keep you healthy. The idea is that the audience trusts the speaker or writer and so will be more likely to accept their argument.
