articulate
"Articulate" is a word that works as both an adjective and a verb, so it has two main sides to it. As an adjective, it describes how well someone expresses themselves. As a verb, it describes the act of expressing or pronouncing something. Here are the most important senses to know.
When someone is articulate, they are very good at putting their thoughts into words. They speak or write in a way that is clear, organized, and easy to understand. Think of a person who can explain a complicated idea so well that everyone in the room immediately gets it — that person is articulate.
everyday language, communication · Modern, widely used
In a more technical or scientific context, articulate describes something that has joints or sections connected in a way that allows movement. You might see this used to describe bones, robotic arms, or certain animals. Think of an articulated lorry (a large truck) — it bends in the middle because it has a joint connecting two sections.
