Etymology

Origin of gyro1

First recorded in 1905–10; independent use of gyro-

Origin of gyro2

1970–75; < Modern Greek gŷros literally, turn, revolution; see gyre

Origin of gyro-3

< Greek gŷros ring, noun use of gȳrós round

Explanation

A gyro is either a tool designed to stabilize compasses and other navigation systems — or it's the name for a delicious sandwich. Just make sure you don't get these two kinds of gyros confused! Gyro is frequently used as shorthand for gyroscope, a device that can determine the direction or speed of an attached object. When the word is pronounced YEE-roh, you've got an entirely different gryo, a Greek sandwich made with roasted meat and sauce (and sometimes French fries) stuffed into a round pita pocket. Both meanings have the same Greek root, gyros, "a circle."
