stairs

Also known as staircase, flight of stairs, stairway, steps

Stairs are a structure designed to bridge a large vertical distance between lower and higher levels by dividing it into smaller vertical distances. This is achieved as a diagonal series of horizontal platforms called steps which enable passage to the other level by stepping from one to another step in turn. Steps are very typically rectangular, but may instead be straight, curved, or may consist of two or more straight pieces connected at angles.

AI overview

Stairs are structures made of a series of steps that allow people to move between different levels by breaking up a large vertical distance into smaller, manageable climbs. They typically consist of rectangular horizontal platforms arranged diagonally, though they can also be straight, curved, or made of multiple angled sections.

Types of stairs include staircases (also called stairways) and escalators. Some alternatives to stairs are elevators (also called lifts), stairlifts, inclined moving walkways, ladders, and ramps. A stairwell is a vertical shaft or opening that contains a staircase. A flight (of stairs) is an inclined part of a staircase consisting of steps (and their lateral supports if supports are separate from steps).
