Etymology

Origin of intellectual

First recorded in 1350–1400; Middle English, from Latin intellēctuālis, equivalent to intellēctu-, stem of intellēctus intellect + -ālis -al ¹

Explanation

The adjective intellectual describes something related to or using the mind or intellect. Your creative pursuit of singing in a rock band is different from your intellectual interest in 16th-century drama. Intellectual is often used to describe intensive reasoning and deep thinking, particularly in relation to subjects that tend to spark deep discussion, such as literature or philosophy. An intellectual is also a noun for a cerebral or brainy person who engages in deep thinking, like Plato, Albert Einstein, or your classmate who can speak at length about the relationship between French existentialism and ice hockey.
