What it does
Enchant is a keyword on Auras that tells you what the Aura can legally be attached to. "Enchant creature" means it must go onto a creature; "Enchant land" means a land, and so on. When you cast an Aura, you choose a legal target matching its enchant restriction, and it enters attached to that permanent (or player, for some Auras).
The big nuance: Enchant defines a targeting and legality requirement that's checked continuously. If the enchanted permanent stops being a legal object for the Aura—say it loses creature type, or gains protection or hexproof from the Aura's controller—the Aura falls off and goes to the graveyard as a state-based action. You can't move an Aura freely; it only relocates via effects that explicitly say so.
In Commander, watch for Auras targeting opponents' creatures (like removal Auras): protection, shroud, or bounce can strand or kill your Aura, costing you card advantage.
