Hangul syllable 걪

No; 걪 is a syllable block, not a word. In Korean writing, it contributes one syllable inside a word; the surrounding word supplies the meaning. On its own, it gives you a sound but no fixed lexical meaning.

Hangul was designed to write Korean in a script suited to its sounds, while written Korean had made extensive use of Chinese characters. King Sejong introduced it in 1443; the 1446 book Hunminjeongeum explained how its letters and syllable blocks work. The 1996 date marks Unicode encoding of this block, not the origin of Hangul.

What is 걪 made from?

Three Hangul jamo form the block. The input forms are ㄱ, ㅒ, and ㅈ: an initial consonant, a vowel, and a final consonant. Unicode’s decomposed normalized form stores the corresponding leading, vowel, and final jamo as three code points, so raw string comparisons can differ until text is normalized.

Why does 걪 look different?

The font determines the strokes you see. Hangul-capable fonts can draw 걪 differently; a font without Hangul coverage may show a missing-character box. A typeface changes the glyph’s design, not the character’s encoded identity.
