A lost-and-found is a place — a desk, a room, or even a box — where staff keep things people have left behind, until the owner comes to claim them. Schools, stations, museums, and pools often have one. American English likes “lost and found” or “lost-and-found.” In Britain people often say “lost property” for the same office, though they will still understand lost-and-found. You can talk about the lost-and-found as the place itself.
