Who was Osiris's wife and sister?

The story behind the answer

Isis is both the wife and sister of Osiris. In the central Egyptian myth, after Osiris is murdered by his brother Set, Isis uses powerful magic to reassemble and briefly revive him, conceiving their son Horus. Osiris then becomes lord of the underworld, while Isis embodies magic, motherhood, and kingship—her name’s hieroglyph is a throne, signaling her role in legitimizing pharaohs.

To distinguish the options: Nephthys is their sister and often linked to mourning (usually paired with Set), Hathor is the goddess of love and music, and Sekhmet is a fierce lioness of war and plague. Memory tip: “Isis is Osiris’s sis” and spouse—the throne on her head helps you picture her as queen beside the king.
