Hangul Syllable Cyogg

It is one Hangul syllable block, and “cyogg” is a component label.

Hangul letters that combine inside syllable blocks are called jamo. The name “cyogg” joins the short component labels for initial consonant ᄎ, vowel ᅭ, and final consonant ᆩ; it describes how the block is built, not what a Korean word means.

Hangul was designed in fifteenth-century Korea to represent Korean speech. The royal chronicle Sejong Sillok first records Hunminjeongeum, the new writing system, in 1443; an explanatory book followed in 1446. Chinese characters were used in Korean writing before Hangul. Hangul instead groups alphabetic letters into syllable blocks, and its name became widely used after 1928.

Why does 쵺 look different in different fonts?

A font can move the parts without changing 쵺.

Hangul typefaces fit letters into a compact square cell, adjusting their size, spacing, and placement. Compare the whole syllable block; a consonant's proportions can change with the font.

Unicode also represents 쵺 in a canonical decomposed form, ᄎ + ᅭ + ᆩ, which software can compose into one block. Text normalization, selection, or search may expose either representation; both encode the same syllable.
