Hangul syllable dwac

By itself, 돷 is a syllable block; its Korean word supplies context.

Hangul blocks represent syllables within Korean writing. A block's role comes from its word; a lone 돷 gives too little context for a reliable reading, so ask the sender what they meant.

The earliest documented account of this syllable-block system is the Hunminjeongeum, published in 1446. Hangul was designed for writing Korean with consonant and vowel letters; before it, formal writing often used Chinese characters (Hanja) and Classical Chinese. Hangul is not descended from Hanja: its blocks combine sound letters rather than encode pictures.

How is 돷 built?

It combines ㄷ, ㅘ, and final ㅊ in one block.

A Korean IME (input method editor) can build the block as you type: enter ㄷ, ㅗ, ㅏ, ㅊ; ㅗ and ㅏ combine as ㅘ. Unicode can represent the syllable as one precomposed block or as separate Hangul letters, called jamo, that join when rendered.

Fonts arrange the letters inside a syllable cell, so proportions and strokes can vary without changing the character. Hangul type has adapted to movable type (reusable printing letters), typewriters, and digital fonts, each arranging letters within that cell.
