Professionals are those who do something, especially something that people can see, read, or hear about regularly, and who have something that can make them money.
An occupation is something like a job. People in professions are more likely to have a job, so if you have a job, you are in a profession.
Professionals aren’t necessarily just the ones working in a certain profession. They can also be the ones who have a title such as an accountant or a lawyer.
The two professions I listed above are what I would consider to be the core of our world. In general, we would classify professionals as those people who work for or hold an office for a company or a corporation. This is similar to the definition we use for an academic or a teacher.
An academic has someone as a teacher or a professor that does not work for that company or corporation. An academic can also be someone who holds an office or a title in a company but does not actually work for that company.
To be a professional, I would classify you as a person who performs any of the above listed activities. In general, our world is organized such that, for example, a doctor or a lawyer is in charge of a hospital but they don’t actually physically work for the hospital, nor do they actually have a physical office for the hospital. A dentist, however, is in charge of a hospital but does actually physically work for that hospital.
The term “professional” generally refers to a person who has earned an expert level of knowledge or credentials in a field or profession. In other words, a lawyer is a lawyer but does not necessarily work for a law firm. A teacher, although a person with a high school diploma or a college degree, can still be a teacher but can be considered a teacher.
A trade is a business or profession. A profession, although it may be a specialized one, is one performed by a specialized person who has earned an expert level of knowledge or credentials in a particular field or profession. A trade, therefore, is a business but is also a profession performed by someone who has earned an expert level of knowledge or credentials in the same field or profession.
A license, a title, or an official position is a legal designation or official position. A profession is a recognized occupation.
Professional is the most common term for this type of office. A trade or business may be called a trade or a service. A business may be called a business or a business.
