Etymology

It is inherited from Proto-Indo-European *bʰuH-tís, an action noun of the root of φύω (phúō, “to bring forth, grow”), with the suffix -σις (-sis).[1] Cognate with Sanskrit भूति (bhūtí, “existence, power”) and Proto-Slavic *bytь (“essence”).[1]

Earliest recorded meaning

Homer uses it only once, in the Odyssey (10.303), for the physical nature of a thing.[2][3]

Semantic evolution

Empedocles uses it for origin and coming into being, and Plato and Aristotle say that φύσις is meant to signify “genesis”.[4] For persons it was birth, so that a father “by nature” differed from an adoptive one.[4] The Hippocratic writers used it for growth.[4] From Aeschylus on it meant a person's physique and appearance, and in Pindar one's innate disposition and character;[2] Thucydides speaks of “human nature”.[2]

Heraclitus, Plato and Xenophon used it for the inherent character of a thing, and φύσει meant “by nature, intrinsically”.[2] It became the natural order of things, set against human convention.[2] In the New Testament, Galatians 2:15 has “we who are Jews by nature”, that is by birth.[5] The modern form is Modern Greek φύση (físi).[6]
