It's likely you meant "taciturn", which describes someone who is uncommunicative and reserved.
Here's a breakdown:
* Taciturn: A person who speaks very little, often appearing to be quiet or uninterested in conversation.
For example:
* "The old man was taciturn, rarely speaking unless spoken to."
* "She had a reputation for being taciturn and difficult to get to know."
