peekaboo

Peekaboo is the familiar game where you hide your face, usually with your hands, and then show it again to make a baby or small child laugh. The fun comes from the tiny surprise of someone disappearing for a moment and then coming back. It is often one of the first games babies enjoy, and people sometimes connect it with learning that things still exist even when they are out of sight.

The word can also describe something that appears and disappears in a playful way. For example, a child's face might pop out from behind a curtain in a peekaboo moment. This wider use is still light and playful, but the main meaning is the simple game of hiding and revealing.

"Peekaboo" is, at its heart, a game of disappearing and coming back. Someone covers their face or hides for a moment, then suddenly appears again, often saying "Peekaboo!" The game is especially common with babies and toddlers because the quick surprise often makes them laugh and want the game to happen again and again.

This is more than a silly little game. Many people connect peekaboo with early learning, because it gives babies practice with the idea that a person or thing still exists even when it cannot be seen. When a face vanishes behind two hands and then returns, the child begins to understand that hidden does not mean gone forever.

By extension, "peekaboo" can describe anything that shows itself briefly and then hides again in a cute or playful way. A baby might play peekaboo from behind a sofa, or the sun might seem to play peekaboo from behind the clouds. Even in these wider uses, the feeling is usually gentle, light, and tied to the idea of hiding and revealing.

So, whether it is a parent making a child giggle, a toddler popping out from behind a chair, or a playful image of something appearing for a moment, "peekaboo" carries the same simple sense of surprise, return, and delight.
