Hangul syllable Dyeos

Switch to Korean input, then enter ㄷ, ㅕ, and ㅅ in order.

On the standard two-set Korean layout, Dubeolsik, E, U, and T enter those letters in order. The Korean input method groups them into one syllable block. With English input active, the same keys produce EUT.

In software, 뎟 is the same syllable encoded as three Hangul letters. Unicode normalization can recompose that sequence as 뎟; the font determines the visible outline.

What are the parts of 뎟?

It is one Hangul syllable block made from three letter parts. Hangul puts an initial consonant and a vowel together, then may add a final consonant; 뎟 has all three.

When was Hangul first recorded?

The first system-level record dates to 1443. It attributes the 28-letter script to King Sejong and calls it Hunminjeongeum.

A book of the same name, published in 1446, explains the script's purpose and how its letters form syllables. Its stated aim was to make Korean easier to write for people who had relied on Chinese characters.

Earlier names included jeongeum (“correct sounds”) and eonmun (“vernacular writing”); after 1894, gukmun (“national writing”) and gukseo were common. The name Hangeul is thought to have entered use in the early 1910s and was widespread by 1928.
