physis

Physis (φύσις) is a Greek theological, philosophical, and scientific term usually translated into English as "nature". In the Odyssey, Homer uses the word once (its earliest known occurrence), referring to the intrinsic way of growth of a particular species of plant. In other very early uses it had such a meaning: related to the natural growing of plants, animals, and other features of the world as they tend to develop without external influence. But in the pre-Socratic philosophers it developed a complex of other meanings.

The word morpheme -physis occurs at the ends of some anatomical names, usually of projecting parts of bones, and in some names of animals (e.g. Coelophysis). If with a Greek preposition, as in e.g. X-physis, it means "a process which sticks out in the direction X"; otherwise it means "form", "nature". It is from Greek φυσις from the verb φυω = "I bring forth", "I produce", "I make to grow".
