taciturn

Taciturn describes a person who is habitually silent, reserved, or disinclined to talk. Imagine someone sitting quietly in the corner of a room, not out of shyness or anger, but simply because they find little value in idle chatter and prefer to keep their thoughts to themselves. The word carries a slightly sophisticated tone and is often used to describe characters in literature or stoic individuals. While it implies a lack of speech, it does not necessarily mean the person is unfriendly; it suggests a personality defined by brevity and introspection.
