rear

"Rear" often points to the back part of something, the part that is behind. You see it in phrases like a car's rear door, the rear entrance of a building, or a person "bringing up the rear" at the end of a group. It can also mean a person's bottom in a polite or playful way. But "rear" is also a verb. To rear a child or an animal means to raise and care for it while it grows. And when a horse rears, it lifts itself up onto its back legs.

The word "rear" moves through English in a few clear ways, all tied to the idea of the back part or of something being raised up. Most often, it names the part furthest from the front: the rear of a car, the rear of a building, the rear seats, or the rear end of a line. In travel, daily life, and even military language, it helps show position. A "rear guard" protects from behind, and the person "bringing up the rear" is the one at the very end.

As a verb, "rear" has two important uses. One is about raising living things. Parents rear children; farmers rear cattle, sheep, or chickens. Here, the word means feeding, caring for, and helping them grow. The other verb use is about sudden upward movement. A horse can rear when it rises onto its hind legs, often because it is excited, frightened, or resisting control. This sense also appears in the expression "rear its ugly head," which means that a problem appears again, often after being hidden for a while. The word can also be used politely for a person's bottom. Taken together, these uses make "rear" a word about what is at the back, what is cared for as it grows, and what lifts up sharply.
