What 읔 means
Alone, 읔 can read as a groan; in 키읔, it names ㅋ.
In Hangul, the Korean alphabet, ㅋ is named 키읔, so 읔 is its final syllable. The name shifted from 키 in 1527 through an intermediate form in 1909 to 키읔 by 1933 (1527 → 1909 → 1933).
Around 2018, standalone 읔 was used in online and game writing as a pained or frustrated groan, like “ugh” or “ow.”
Neutral inside the Korean consonant name 키읔; informal and context-dependent as a groan.
In 2018, 읔엨 was linked to a joke mocking disabled people; avoid aiming it at a person.

1Why does 읔 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
