The Vietnamese word "lão luyện" is an adjective that means "expert" or "experienced." It describes someone who has a high level of skill or knowledge in a particular area due to a lot of practice and experience.
Cô giáo này rất lão luyện trong việc giảng dạy.
(This teacher is very experienced in teaching.)
Anh ấy là một cầu thủ lão luyện, đã chơi bóng đá hơn 10 năm.
(He is an experienced player who has been playing football for over 10 years.)
In more sophisticated contexts, "lão luyện" can be paired with nouns to provide a more detailed description: - Lão luyện trong nghề (expert in the profession) - Lão luyện trong nghệ thuật (expert in the arts)
While "lão luyện" primarily means "expert" or "experienced," it can also imply that a person has a deep understanding or mastery that comes from many years of practice.
