Hangul Syllable Hi

Use a Korean IME: enter ㅎ, then ㅣ. With Korean composition active, the input method combines the consonant and vowel into one block. Without composition, the two keyboard-compatible letters can remain separate.

The syllable can also be stored as the joining forms ᄒ and ᅵ rather than one precomposed block. A font or editor with weak Hangul support may display those forms apart. They are different characters from the keyboard-compatible ㅎ and ㅣ.

What does 히 mean in a Korean word?

Its contribution depends on the whole Korean word.

The ending -히 forms adverbs in 조용히 (“quietly”) and 특히 (“especially”), but not every appearance of 히 is automatically that ending. In 안녕히 가세요, the full phrase is a polite farewell to someone leaving.

Hangul was built for Korean syllable blocks

Hangul was created in 1443 and promulgated in 1446 as a Korean alphabet intended to make writing easier to learn. Its founding guide describes combining consonant and vowel letters into syllable blocks like 히. Those dates mark the alphabet’s creation and promulgation.

Before Hangul, Korean writing used systems based on Chinese characters, including idu, hyangchal, and gugyeol. These are earlier Korean writing traditions; 히 belongs to Hangul’s alphabetic syllable-block system.
