Notes

The provided reference context includes a separate, technical, and less common meaning: "to cut or shape with a die." This is a transitive verb (e.g., die out leather for belts) and is considered a different sense of the verb "die" (related to tooling/manufacturing), not a meaning of the phrasal verb "die out" in common modern usage. The primary and almost exclusive meaning of the phrasal verb "die out" is "to become extinct."
