connector
Something or someone that joins separate things together.
A connector is something that joins two or more things together. An electrical connector might link wires so electricity can flow between them, while a plastic connector piece in a building toy like LEGO allows you to attach different parts into a larger creation. In plumbing, connectors join pipes so water can travel through an entire system.
People can be connectors too. A connector is someone who knows lots of different people and introduces them to each other. If you have a friend who always brings together kids from different classes or activities, that person is acting as a connector. They help create new friendships and opportunities by linking people who might not otherwise meet.
In writing and speaking, connectors are words or phrases that link ideas together. Words like “however,” “therefore,” “meanwhile,” and “for example” are connectors that help your reader follow your thinking from one sentence to the next. Without these connecting words, your writing might feel choppy, like separate islands instead of a smooth path.
Whether it's a physical object, a person, or a word, a connector's job is always the same: bringing separate things together into something larger or more complete.
