That's very vague, and I'm not a native speaker, but I'll do my best! The most important thing is to distinguish between politeness and honorifics. I've had Korean teachers who called both "honorifics" but that's not correct. You use honorifics when you're showing respect to the subject of your sentence, not necessarily who you're talking to. Honorific speech usually shows up in an "infix" you put in a verb -shi- (I don't know how much Korean you know so I will use Roman letters). Politeness depends on who you're talking to. You see politeness in the endings of verbs, like using -yo at the end, or -mnida. -yo is equally as polite as -mnida, but -mnida is more formal. You also change the way you say "I" when you are being polite. Na is blunt, and impolite, Jeo is polite. Neo (pronounced Naw) is impolite for "you"; when being polite, Koreans don't say you, they try to use a title, or say Mister, Miss, etc, Is that what you were looking for?
