Logos, pathos, and ethos are the three modes of persuasion, or ways to persuade people. More specifically:
Logos appeals to the audience’s reason. It involves presenting logical arguments, statistics, and facts.
Pathos appeals to the audience’s emotions. It involves influencing the audience’s emotions through storytelling or evocative language so that they are more likely to accept the speaker’s viewpoint.
Ethos appeals to the speaker’s or writer’s credibility. It involves establishing the speaker’s or writer’s authority, trustworthiness, and moral character, making the audience trust them.
