Another word for stubborn is obstinate. Someone who is obstinate refuses to change their mind or course of action, even when faced with good reasons to do so.
For example, if someone is obstinate about their opinions during a discussion, they may disregard facts or alternative viewpoints simply because they are set in their ways. This characteristic can sometimes be viewed negatively, as it can lead to conflicts and an unwillingness to compromise. However, in some contexts, being obstinate might also reflect determination and persistence, especially when pursuing goals.
