Etymology

Origin of component

First recorded in 1555–65; from Latin compōnent- (stem of compōnēns, present participle of compōnere “to put together”), equivalent to com- com- + pōn(ere) “to put” + -ent- -ent

Explanation

It's the Ikea curse: You spend four hours figuring out how to piece together your new furniture, only to be left with one random component, or part, that doesn't seem to fit anywhere. It's not surprising that component is related to a Latin word that means "to put together." You simply can't put something together without all of the correct components. Technically speaking, a component is an element of a system or a part of a machine. But a component can also be a factor or ingredient, such as the components of a decision or the components of a really good chocolate cake.
