What 땀 means
땀 means “sweat” in Korean.
It also means effort in 땀을 흘리다 (“work hard”) and 땀을 빼다 (“struggle through difficulty”). Another sense is one sewing stitch, as in 한 땀 한 땀 (“stitch by stitch”).
The earlier spelling ᄯᆞᆷ appears in the 1459 Korean work Wŏrin seokbo. Hangul is the writing system for Korean and was designed to be accessible. Unicode composes 땀 from ᄄ, ᅡ, ᆷ into one block; fonts may position those letters differently.

Questions people ask
1Why does 땀 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.
