Hangul syllable Yog

It usually means abusive language or a rebuke.

욕 can also mean disgrace or colloquial trouble. 욕하다 means to swear at someone; 욕먹다 means to be criticized or blamed.

Hangeul was created to write Korean, and 욕 is an ordinary syllable in that system, not a purpose-built swear sign. Its corresponding Hanja is 辱, the Chinese character used in Korean writing, linking the word to insult and disgrace. A historical Korean grammar records 욕-, a related older spelling with a vowel no longer used in modern Korean.

What does 욕 mean when someone sends it?

By itself, 욕 usually sounds like a hostile burst of profanity.

That makes it risky with a boss, teacher, client, or stranger. Close friends can use rough language to signal solidarity, but the relationship and target matter. A 2014 comparative review reports heavier swearing among adolescents and greater sensitivity among adults; that broad pattern cannot tell you how one Korean friend will read 욕.

How do I type 욕?

Type d-y-r with Korean input active.

On the standard two-set Korean layout, d-y-r maps to ㅇ-ㅛ-ㄱ; the input method joins them as 욕. In English mode, those keys produce Latin letters instead.
