intro

"Intro" is short for "introduction." It usually means the opening part of something, such as a song, a book, a talk, or a video. It is the first part people see or hear, and it helps set the tone for what comes next. You might hear someone say, "That song has a great intro," or "I'll start with a quick intro to the topic." It is also often used for a beginner class, such as "Intro to Psychology."

The word "intro" is a shortened form of "introduction." Most often, it means the beginning or opening part of something larger. It is the part that comes first and helps people get ready for what follows.

In music, an intro is the part before the main singing or main theme begins. In a book, article, speech, presentation, or video, it can be the opening section that gives a little background and shows the direction of the piece. A strong intro catches attention, gives some context, and leads naturally into the main content.

The word is also used for a short explanation of a subject: "Here is a quick intro to the system" means a brief first look, not a deep study. In schools and universities, "intro" often names a beginner-level course, such as "Intro to Biology" or "Intro to Design." In that use, it tells you the class is meant as a starting point.

In everyday English, "intro" is common in casual speech and writing because it is shorter and more natural than "introduction" in many situations. Whether it is the first bars of a song, the first lines of a talk, or a simple beginner course, the word points to a starting point: the moment something begins and invites you in.
