Uses
Because many different Hanja--and thus, many different words derived from Hanja--often share the same sounds, two distinct Hanja words may be spelled identically in the phonetic Hangeul alphabet. Thus, Hanja are often used to clarify meaning, either on their own without the equivalent Hangeul spelling, or in parentheses after the Hangeul spelling as a kind of gloss. Hanja are often also used as a form of shorthand in newspaper headlines, advertisements, and on signs. Some details of use follow.
Hanja in Print Media
Sino-Korean characters are used most frequently in academic literature, where they often appear without the equivalent Hangeul spelling. Either all words of Sino-Korean origin may be spelled using Hanja (which is extremely rare), or only those words with a specialized or ambiguous meaning may be printed in Hanja (which is the more common way of using them.) In books and magazines, Hanja are generally used sparingly, and only to gloss words already spelled in Hangeul when the meaning is ambiguous. Hanja are often used in newspaper headlines instead of Hangeul to eliminate the ambiguity typical of newspaperese in any language. Hanja appear frequently in dictionaries and atlases; see below.
Hanja in Dictionaries
In modern Korean dictionaries, all entry words of Sino-Korean origin are printed in Hangeul and listed in Hangeul order, with the Hanja given in parentheses immediately following the entry word. (A similar practice is followed in Japanese dictionaries.) This practice helps to eliminate ambiguity, and it also serves as a sort of shorthand etymology, since the meaning of the Hanja and the fact that the word is composed of Hanja often help to illustrate the word's origin.
As an example of how Hanja can help to clear up ambiguity, many homophones are written in Hangeul as 수도 (sudo), including:
- 修道 "spiritual discipline"
- 受渡 "receipt and delivery"
- 囚徒 "prisoner"
- 水都 "city of water" (e.g. Hong Kong and Naples)
- 水稻 "aquatic rice
- 水道 "aquatic duct"
- 隧道 "tunnel"
- 首都 "capital (city)"
- 手刀 "knife of hand"
