What 첨 means
Alone, 첨 means “first time” or “beginning.”
It shortens 처음: 첨부터 means “from the start,” and 첨으로 means “for the first time.”
In compounds, 첨 can represent 添 (“add”), a Chinese character used in Korean words: 첨가 is addition, 첨부 attachment, and 첨삭 editing with corrections.
Alone, 첨 depends on context; 처음 is clearer for readers who may not know the shortcut.
In compounds, don't assume 첨 means “first.”

Questions people ask
1Why does 첨 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.
