junction

The noun junction refers to a meeting or a joining of some kind. If you live at the junction of Main and State streets, then your house is where those two streets meet.

Junction often refers to the point where streets or railway lines come together, but it can describe other things that are joined, especially things that are in motion or transmit other things. For example, your body has nerve junctions — the places where your nerves come together. You may go swimming at the junction of two rivers. Junction can also refer to something that connects things, like a junction you use to connect electrical cords.
