gyre

Borrowed from Latin gȳrus (“circle; circular motion”), from Ancient Greek γῦρος (gûros, “circle; ring”), from Proto-Indo-European *gew- (“to bend; to curve”). The English word is a doublet of gyro and gyrus.

From Late Middle English giren (“to turn (something) away; to cause (something) to revolve or rotate; to travel in a circle”), from Old French girer (“to turn”), and directly from its etymon Latin gȳrāre, the present active infinitive of gȳrō (“to turn in a circle, rotate; to circle or revolve around”), from gȳrus (“circle; circular motion”) (see etymology 1) + -ō (suffix forming regular first-conjugation verbs).
