The Vietnamese word "bướng" is an adjective that means obstinate, stubborn, or self-willed. It describes a person who refuses to change their mind or behavior, even when they are wrong.
"Cậu ấy rất bướng."
"Dù đã sai, nhưng cô ấy vẫn bướng và không chịu nhận lỗi."
In some contexts, "bướng" can also imply a sense of rebelliousness, where a person not only refuses to conform but may actively resist authority or expectations.
