Transit means movement or travel from one place to another, especially when passing through or across a space. When a package is in transit, it's on its way but hasn't arrived yet. When astronomers observe Venus in transit across the sun, they're watching the planet pass between Earth and the sun, creating a tiny dark spot visible through telescopes.

The word often appears in public transit or mass transit, which means transportation systems like buses, subways, and trains that carry many people around a city. Public transit helps millions of people get to work, school, and appointments without needing their own cars. Cities like New York, London, and Tokyo are famous for their extensive transit systems that move enormous numbers of people efficiently every day.

Transit can also describe the act of passing through a place without staying. An airport transit lounge is where travelers wait between connecting flights. If you're driving cross-country and pass through Nebraska without stopping, you're in transit through that state.

The word emphasizes that middle stage: not where you started and not yet where you're going, but the space in between.
