dirt

Dirt is earth or soil — it's the substance that makes up the dry surfaces of our planet. Gardeners spend a lot of time digging in the dirt, planting seeds and pulling up weeds.

Dirt is the fine rock that makes up soil, but it also means anything unclean: "Do something about the dust and dirt in this room before our guests arrive!" When you know something embarrassing about another person, especially juicy gossip, you can call that information dirt as well — this meaning was coined by Ernest Hemingway in 1926. The word comes from the Old English drytt, "mud, dirt, or dung."
