Etymology

Origin of quadruple

1325–75; Middle English < Latin quadruplus; cf. quadru-, duple

Explanation

When something is made up of four parts, you can describe it using the adjective quadruple, like a young gymnast's quadruple somersault. A common use of quadruple is in the medical term "quadruple bypass," which is a type of heart surgery that involves all four chambers of the patient's heart. You can also use quadruple to mean "four times as many," as when you order a quadruple-shot latte, with four shots of espresso. The Latin root word quadruplare, "make fourfold," comes from the suffix quadri-, or "four."
