What 썽 means
Not by itself; the surrounding word decides.
In 2025, official guidance gave 의외성 the Korean 썽 pronunciation [의외썽]. In compounds, written 성 can sound like 썽, so 썽 is often a pronunciation clue rather than the correct spelling.
As of 2026, regional sources record 썽내다 in anger-related dialect use, against standard 성내다. 성내다 appears as 셩내다 in the 1576 Sinjeung yuhap, a reminder that spelling and sound have diverged before.
Neutral as a syllable; regional or phonetic outside standard spelling.
Do not replace every 성 with 썽.

1Why does 썽 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.
