- Hasoseo-che (하소서체): The most traditional and respectful level of speech, used in formal situations and to elders or superiors. It was mostly used to address royalty in the past, but can be seen in historical dramas or religious texts.
- Hasipsio-che (하십시오체): This level of speech is right between formal and casual, providing respect without going overboard. Strangers typically use this during their first few encounters, and it’s often used in public speeches, business, and people in the service industry.
- Haeyo-che (해요체): This is the most common polite level of speech, and it can be used to address strangers and the elderly. Foreigners are often urged to learn this form because it’s ideal for everyday situations.
- Hao-che (하오체): This is an outdated style of formal speech that you can find in historical K-dramas. It can be used to address people that are the same age as you or younger, and it's mainly seen in writing.
- Hage-che (하게체): This is an uncommon, casual-leaning style of speech that middle-aged people use to address other adults that they’re close to. It can also be used by older people to address younger people.
- Haera-che (해라체): This is a casual level of speech that’s still a bit formal. It’s most often used in writing, but not commonly used in conversation.
- Hae-che (해체): This is the most informal level of speech, used with friends, family members, and close acquaintances. Avoid using it in front of someone of a higher rank.

In LGBTQ+ relationships, honorifics may be used more loosely. For example, boyfriends may both call each other "hyung" or playfully call each other "unnie" (like how gay men might call each other "girl" in English). Similarly, girlfriends may call each other "unnie."
