Hangul syllable Bbyeobs

No; it is a Korean syllable block, not a complete word.

Hangul, the Korean writing system, writes words with blocks like this: initial ㅃ, vowel ㅕ, and final consonant cluster ㅄ. The block marks one syllable; the word containing it supplies the meaning.

Hangul was developed under King Sejong to write Korean through letters that represent speech sounds and combine into syllable blocks. The Sejong Sillok, a royal chronicle, records the script in 1443; the Hunminjeongeum Haerye, a guide to its design, appeared in 1446. These dates belong to Hangul as a writing system, not this individual block.

How do I type 뼚?

Use a Korean 2-set (Dubeolsik) keyboard layout.

Press Shift+Q, U, Q, T. The input method joins ㅃ + ㅕ + ㅂ + ㅅ into one syllable block, combining the last two consonants into final cluster ㅄ.

Fonts can draw the same encoded block in different styles. A decomposed form uses separate joining jamo (Hangul letters); it depends on shaping support, which varies among apps and fonts.
