A personal name appearing in the genealogy of Judah's descendants. Tappuach was a son of Hebron according to 1 Chronicles 2:43. The name is identical in form to the Hebrew word for 'apple' or 'apple tree,' though whether there's an etymological connection is uncertain. The Septuagint renders it as Θαπους or Θαφφου, showing variation in Greek transliteration. This is distinct from the place name Tappuach found elsewhere in Scripture.
