坟
fén · HSK 7
grave
⚰️ 土 (earth) + 文 (writing) = inscribed earth, a marked grave
A grave is earth with writing on it — the tombstone inscription. The radical 土 gives you dirt, and 文 gives you the 'fen' sound plus the idea of carved text marking where someone rests.
坟 — earth 土 + 賁 (phonetic, 'big/adorned')
A semantic-phonetic compound: 土 ('earth') gives the meaning of a burial mound, while 賁 supplies the sound (originally close to 'bēn/fén'). The character originally referred to a raised earthen mound over a grave, later generalizing to mean 'tomb' or 'grave' in modern usage.
