## Origin

Recorded from the 1580s, from "physic," via Middle English phisik and Old French fisike ("natural science, art of healing"), from Latin physica ("study of nature"). This came from Ancient Greek phusikḗ ("natural, physical"), from phúsis ("nature, origin") and phúō ("to produce, grow"), ultimately from the Proto-Indo-European root *bʰuH- ("to appear, become, rise up").
