physical

The word "physical" originates from the Latin physicus, meaning "of nature" or "natural science," which itself was borrowed from the Greek physikos, derived from physis (φύσις), meaning "nature" or "origin." The Greek root phy- is linked to the verb phyesthai (to grow, to come into being), tracing back to the Proto-Indo-European root bʰuH-, meaning "to become, grow, or appear." Initially, "physical" in English pertained to natural science and medicine (as in "physical world" or "physical laws"). Over time, its meaning specialized to distinguish the material, bodily, or tangible aspects (the "physical" body) from the mental, spiritual, or abstract, reflecting a conceptual division between the natural, observable realm and the internal world of thought.

It forms adjectives meaning "of or relating to".
