What 옹 means
Usually, 옹 is an informal yes with a marked texting tone. A 2018 guide calls it a possible, uncommon yes; a 2020 NATE discussion includes it among casual replies. The choice marks tone and relationship, not a different answer.
Hangul was created in 1443 and explained in 1446 to make Korean easier to write than with Chinese characters. A Hangul syllable combines consonants and vowels: 옹 has ㅇ at both ends around ㅗ. Hanja are Chinese characters used in Korean; several are read as 옹.
Casual and tone-sensitive; best with people who share that chat style.
Can I send 옹 to my boss? No; use a polite yes instead.
