physic

From Middle English phisik, from Latin physicus, from Ancient Greek φῠσῐκός (phŭsĭkós, “natural; physical”), from φύσις (phúsis, “origin, birth; nature, quality; form, shape; type, kind”), from φῠ́ω (phŭ́ō, “grow”), ultimately from Proto-Indo-European *bʰuH- (“to appear, become, rise up”).

From Middle English fysike (noun) and phisiken, fisike (verb; from the noun), from Old French fisike (“natural science, art of healing”), from Latin physica (“study of nature”), from Ancient Greek φυσική (phusikḗ), feminine singular of φῠσῐκός (phŭsĭkós, “natural; physical”), see above.
