Here is a worksheet on the Greek word roots gyr and gyro. They mean, simply, circle. You’ll find these roots at the basis of words like gyroscope, gyro, and gyrate, which aren’t exactly high-frequency words in English. Nor are gyrocompass, autogiro, or spirogyra, which also grow from these roots. Still, if the book from which I drew both the inspiration and the content for word root worksheets is trustworthy, these are all words which will show up on the SAT and other high-stakes college and graduate school gatekeeping tests.
