What does slide mean?
“Slide” is a versatile English word describing both a physical movement and a presentation element. As a noun, it can refer to a smooth sloping surface, often the chute used in a playground, a photograph or page shown in a presentation, or a small glass specimen viewed under a microscope. As a verb, it means to move smoothly and continuously, usually downward or forward, as in sliding a window open or sliding a book across a table. The word can also imply an abrupt or uncontrolled movement: an object may slide or a person may lose their footing unexpectedly. In everyday use, “slide” is especially familiar from playground equipment and slideshows, while its broader meanings extend to any sustained, easy movement. Its usefulness lies in this combination of literal motion and metaphorical descriptions of presentations, surfaces, and changes in condition.
A smooth, usually inclined surface on which a person or object can move down; a presentation image or page; or a small specimen mounted for examination under a microscope.
"The slides in the lecture were projected onto the large screen."
The sense of a playground chute is especially common in British English; the presentation and microscopy senses are established in both British and American English.
To move smoothly and continuously downward or forward, or to cause something to move in this way.
"The door slid open before she reached it."
The word often suggests movement that is easy, continuous, or not directly controlled by the person or force involved.
The plural is used for individual playground surfaces or chutes, pages or images in a presentation, and microscope specimens.
"The teacher added two slides to the end of her presentation."
The word “slide” covers everything from a playground chute to the images in a presentation—and, less reassuringly, the sudden loss of control that made “slide” a familiar warning.

Where does slide come from?
“Slide” comes from Old English slīdan, meaning “to slip” or “to glide.” The word is related to other Germanic forms and to English words such as “slip,” “slippery,” and “slippage,” which preserve the older sense of losing grip or moving unsteadily. Over time, “slide” came to emphasize smooth, continuous movement rather than only a slipping action.
