Etymology

Origin of concept

First recorded in 1550–60; from Latin conceptum “something conceived,” originally neuter of conceptus “conceived,” past participle of concipere “to conceive,” equivalent to con- con- ( def. ) + -cipere, combining form of capere “to seize”

Explanation

A concept is a thought or idea. If you're redecorating your bedroom, you might want to start with a concept, such as "flower garden" or "outer space." It's a general idea about a thing or group of things, derived from specific instances or occurrences. It often applies to a theoretical idea in science: Einstein's contribution to the concept of relativity. Concept was borrowed from Late Latin conceptus, from Latin concipere "to take in, conceive, receive." A concept is an idea conceived in the mind. The original meaning of the verb conceive was to take sperm into the womb, and by a later extension of meaning, to take an idea into the mind.
