What is an example of Ethos

Ethos is a way an author appeals to the reader/viewer. It is one of the 3 appeals ... Ethos, Pathos and Logos

Ethos is based on credibility and building trust ... so we are looking for facts or things that would make the author worth listening and a credible source.

Example:

Dentists across the world trust and use this toothpaste.

The fact that we know that dentists are endorsing this product adds to the appeal and credibility ... it turn we trust it.
