Someone that uses their mind and exercises their imagination often, and can be specialized. Intellectuals need not be advanced in the english language or literature and they
may come from any walk of life; scientists, for example, tend to have an extensive vocabulary in terms relevant to their own field, while novelists tend to have a wider vocabulary in non-scientific terms. Vocabulary isn't the determining factor of what makes an intellectual though; it is mostly a matter of their ability to
think, create
change, and form
new ideas.
