专业的
A professional person does their job very well and follows the rules of their work.
Explanation at your level:
A professional is a person who works. They are very good at their job. If you are professional, you are polite and you work hard. For example, a doctor is a professional person.
Use professional when talking about jobs. A professional athlete plays sports for money, not just for fun. If you act in a professional way, you are kind and serious at work or school.
Being professional means having the right training for your job. It is a common word in business. You might hear about 'professional development' or 'professional advice.' It means doing things the right way, according to the rules of your job.
In this level, we see professional used to describe conduct. 'That was very unprofessional of him' is a common way to criticize bad behavior. It distinguishes between amateurs and those who have dedicated their lives to a craft.
At the advanced level, professional often implies an ethical dimension. It refers to the standards of a 'profession'—a field requiring specialized knowledge and high moral conduct. It can also describe the quality of an object, like 'professional-grade equipment,' denoting superior performance.
Mastering this word involves understanding the nuance between 'professional' as a status and 'professional' as an attitude. It carries historical weight from its roots in 'professing' a skill. In high-level discourse, it can be used ironically or to emphasize the divide between the dilettante and the expert.

When we call someone professional, we are giving them a big compliment! It means they are not just 'doing' a job, but they are doing it with high standards, skill, and a serious attitude. Whether it is a doctor, a mechanic, or a teacher, being professional suggests they have put in the time to learn their craft properly.
You can also use this word to describe things that aren't for fun or hobbyists. For example, a professional camera is built for high-quality work, not just taking pictures of your lunch. It is all about the level of expertise and the seriousness of the situation.
The word professional comes from the Latin word professio, which means 'public declaration.' Back in the Middle Ages, it was used to describe someone who had taken a vow, like a monk or a nun, to live a specific, dedicated life.
By the 17th century, the meaning shifted to describe people who 'professed' to have special knowledge in a field, like law or medicine. Over time, it evolved into our modern usage: someone who gets paid for their expertise and maintains a high standard of conduct. It is a classic example of how a word can travel from a religious vow to a modern office cubicle!
You will hear this word everywhere in the business world. Common pairings include professional advice, professional development, and professional athlete. It is a very versatile word that works in almost any setting where quality and skill are discussed.
Be careful with the register! While it is a neutral, standard word, calling someone 'unprofessional' is a very strong criticism. It implies they are breaking the rules or acting immaturely. Use it when you want to highlight excellence or, conversely, when someone is failing to meet basic standards.
1. Professional courtesy: A polite act done for someone in the same field. (e.g., Doctors often give each other discounts).
2. Professional hazard: A danger or annoyance that comes with a specific job. (e.g., Sore feet are a professional hazard for nurses).
3. Pro bono: Latin for 'for the public good,' meaning professional work done for free.
4. Go pro: To start doing something as a career instead of a hobby.
5. Professional standard: The level of quality expected in a specific industry.
The word professional is an adjective, but it can also act as a noun (e.g., 'She is a professional'). The stress is on the second syllable: pro-fess-ion-al. It rhymes with words like 'intentional' or 'conventional'.
Remember that it is usually followed by a noun, but it can stand alone as a predicate adjective after linking verbs like 'be' or 'seem'. It is a very stable word with no complex plural forms to worry about!
