From Bulbapedia, the community-driven Pokémon encyclopedia.
An evolution-inducing held item is a specific type of held item that either has no other use besides, or is mainly used in order to cause, the evolution of a Pokémon. Many of these items also require for the Pokémon to be traded with another player, however, some only require the Pokémon to be leveled up.
