The Korean language has a system of linguistic honorifics that reflects the social status of participants. Speakers use honorifics to indicate their social relationship with the addressee and/or subject of the conversation, concerning their age, social status, gender, degree of intimacy, and situational context.
One basic rule of Korean honorifics is "making oneself lower"; i.e., the speaker uses honorific forms and also humble forms to make themselves lower.
There are seven verb paradigms or speech levels in Korean, and each level has its own unique set of verb endings which are used to indicate the level of formality of a situation. Unlike honorifics – which are used to show respect towards someone mentioned in a sentence – speech levels are used to show respect towards a speaker's or writer's audience, or reflect the formality or informality of the situation. They represent a system of honorifics in the linguistic use of the term as a grammar system, distinct from honorific titles.
The names of the seven levels are derived from the non-honorific imperative form of the verb hada (하다; "to do") in each level, plus the suffix che (체), which means "style". Each Korean speech level can be combined with honorific or non-honorific noun and verb forms. Taken together, there are 14 combinations.
Korean is the native language for about 81 million people, mostly of Korean descent. It is the national language of both North Korea and South Korea. In the south, the language is known as Hangugeo (South Korean: 한국어) and in the north, it is known as Chosŏnŏ (North Korean: 조선어). Since the turn of the 21st century, Korean popular culture have spread around the world through globalization and cultural exports.
Beyond Korea, the language is recognized as a minority language in parts of China, namely Jilin, and specifically Yanbian Prefecture, and Changbai County. It is also spoken by Sakhalin Koreans in parts of Sakhalin, the Russian island just north of Japan, and by the Koryo-saram in parts of Central Asia. The language has a few extinct relatives which—along with the Jeju language (Jejuan) of Jeju Island and Korean itself—form the compact Koreanic language family. Even so, Jejuan and Korean are not mutually intelligible. The linguistic homeland of Korean is suggested to be somewhere in contemporary Manchuria. The hierarchy of the society from which the language originates deeply influences the language, leading to a system of speech levels and honorifics indicative of the formality of any given situation.
