Word Story
In everyday use, this word most often refers to the covered storage space at the back of a car, the place where groceries, suitcases and emergency kit all end up. It also names a large travelling case with a rigid lid, the kind once carried onto ocean liners and still sold today as vintage furniture or a coffee-table curiosity. A third sense belongs to trees, where it means the main stem — thick, unbranched, and holding up everything above it. The word has a lighter side too: in the plural it names the short shorts people wear to swim, and it turns up in playful phrases about carrying more than you need. It even appears as a jokey slang reference to someone's rear, a usage that pops up in pop songs and casual banter. In British English the car sense is usually called the boot, a difference worth remembering when you read across the Atlantic.
