Etymology: "Quadrocopter" is built from two parts: "quadro-", a combining form from Latin "quadrus" meaning "four-sided" or "square" (the same root behind "quadrant" and "quadruple"), and "copter", a clipped form of "helicopter." The second element therefore names the basic type of machine, a rotorcraft that lifts by spinning blades, while the first says how many rotors it carries. The compound follows a common English pattern in which a prefix tells you the number of units in a machine, as in "bicycle" or "tricycle." Here the "quadro-" prefix points to the four-rotor layout that distinguishes this design from a single-rotor helicopter. Because the word is a technical coinage assembled from existing parts, its meaning stays transparent: anyone who knows "helicopter" can work out what a quadrocopter is.

Synonyms: drone, quadcopter, UAV
