leadoff

Imagine a baseball game: the leadoff hitter is the first batter to face the pitcher. That player starts the action and tries to get the team going. Outside baseball, leadoff can also describe the opening part of something, such as a leadoff article, question, or remark. It often carries the idea of going first and setting the tone. The related verb is lead off, which means to begin something.

The word "leadoff" comes from baseball. As a noun, it refers to the first batter in the lineup, the player who starts the game or an inning for the team at bat. As an adjective, it describes something that comes first and opens the action, as in a leadoff single or a leadoff spot in the order. The central idea is simple: it points to the person or thing that goes first and sets the tone.

From there, the meaning extends naturally into other areas. In journalism or conversation, a leadoff question, story, or comment is the one placed first to begin things and draw attention. In sports writing, you may read about a leadoff home run, which is a home run hit by the first batter of an inning or game. In these uses, the word still keeps its sense of opening something and creating momentum.

It is worth keeping the forms separate. Leadoff is usually the noun or adjective, while lead off is the verb phrase meaning "begin." So a manager can say that a certain player will lead off, and that player is the leadoff hitter. A speaker can lead off a meeting, and the first comment may be called the leadoff comment. Keeping that difference clear makes the word easier to use correctly.
