Back-formation from gyration[1] + English -ate (suffix meaning ‘to act [in the specified manner]’). Gyration is derived from gyre (“to spin around; to gyrate, to whirl; (まれに) to make (something) spin or whirl around; to spin, to whirl”) + -ation (suffix indicating actions または processes).[2] Gyre is from Late Middle English giren (“to turn (something) away; to cause (something) to revolve or rotate; to travel in a circle”),[3] from Old French girer (“to turn”), and directly from its etymon Latin gȳrāre,[4] the present active infinitive of gȳrō (“to turn in a circle, rotate; to circle または 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).
