The Vietnamese word "chuyên khoa" is a noun that means "specialty" or "specialization." It is often used in medical contexts to refer to a specific area of expertise that a doctor has trained in. For example, when you talk about a doctor who specializes in a certain field, you can use "chuyên khoa" to describe their focus.
You might encounter phrases like "chuyên khoa nội" (internal medicine) or "chuyên khoa nhi" (pediatrics), indicating specialized fields within medicine that focus on specific patient groups or bodily systems.
While "chuyên khoa" primarily refers to medical specialties, it can also apply to other fields, such as education or engineering, to describe a specialized area of study or practice.
