A grate is a piece of metal with holes in it that is used as a lid or some other covering over a larger hole. The main purpose of a grate is to let liquids through, but stop solids getting through. Grates are usually used over drains. Very large grates like the one in the picture are strong enough for cars to drive over, while still letting water drain away.

Gravy is a thick sauce, usually brown that is typically served with meat. Gravy is usually served with roast meat, and contains juices from the meat itself. Today you can buy many pre-made gravies and gravy powders so you can have gravy with anything, without needing meat juices to make it.
Sometimes food is cooked in gravy or makes a gravy as it is cooking, like a stew.
