The story
Gyre is 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; circuit, course’), from Ancient Greek γῦρος (gûros, “a circle, a ring”), from Proto-Indo-European *gew- (‘to bend; to curve’)) + -ō (suffix forming regular first-conjugation verbs).
Today it means
noun The act of turning or whirling, especially around a fixed axis or centre; a circular or spiral motion; rotation.
