1. A rotating mechanism in the form of a universally mounted spinning wheel that offers resistance to turns in any direction.
2. A Greek sandwich: sliced roast lamb with onion and tomato stuffed into pita bread.

A sandwich made from roasted lamb, originally the meat itself, as roasted on a rotating spit, from Modern Greek gyros, "a circle". The "s" was mistaken in English for a plural and so it was deleted; therefore, it went from gyros to gyro.
