A teaser is something designed to create curiosity and excitement by revealing just a hint of what's coming. When a movie studio releases a teaser trailer, they show brief, mysterious clips to make audiences eager to see the full film. A teaser gives you enough information to spark interest but holds back the details, like showing a spaceship landing without revealing who steps out.

Teachers sometimes use teasers too. A science teacher might begin class by saying, “Today we're going to do a dramatic experiment,” without explaining what or how. That teaser gets students curious and focused. Publishers release teaser chapters from upcoming books to build anticipation.

The word can also describe a person who teases others playfully, though this meaning is less common. More often, you'll encounter teaser as something meant to intrigue you: a teaser image, a teaser announcement, or a teaser question on a quiz that hints at harder problems ahead.

The key to a good teaser is balance. It reveals enough to hook your interest but not so much that there's nothing left to discover. Video game companies excel at this, dropping teaser images that fans analyze for clues. A successful teaser leaves you thinking, “I need to know more about that.”
