Etymology

Origin of require

First recorded in 1300–50; Middle English requiren, from Latin requīrere, equivalent to re- re- ( def. ) + -quīrere, combining form of quaerere “to seek, search for”; cf. quest ( def. )


Explanation

Require means to need. You require food, water, and shelter to live, but do you really require that new pair of high-fashion shoes? The verb require comes from Latin root words re-, meaning "repeatedly," and quaerere, meaning "to ask." The word lost the sense of asking and came to mean needing, demanding, or insisting upon something. The law requires that you attend school until you're sixteen; your parents probably require you to finish high school. If you're a waiter in a fancy restaurant and the food has been served, you might ask if your customers require anything else.
