Hangul syllable Ryanh

Enter ㄹ + ㅑ + ㄴ + ㅎ in a Korean input method.

These are jamo—the Korean letters that combine into a syllable block. Here, the input method joins final ㄴ and ㅎ into ㄶ. Select Korean input first; the physical keys depend on your keyboard layout.

What does 랺 mean on its own?

It is one written syllable, not a complete message.

Hangul groups letters into syllable blocks. This one has initial consonant ㄹ, vowel ㅑ, and final cluster ㄶ; the surrounding Korean word supplies its meaning.
