The etymology of the word "physical" can be traced back to the ancient Greek word "physis", meaning "nature" or "natural". In Greek philosophy, "physis" referred to the fundamental nature of things and the study of their properties. The word "physical" itself emerged in English during the late 16th century, combining the prefix "phys-" (related to nature) with the suffix "-ical" (pertaining to).
The term "world" derives from Old English, where it was spelled as "weorold" or "worold". It can be further traced to the Germanic word "weraldaz", meaning "age of man" or "human existence". Over time, "world" evolved to refer to the entirety of existence, the earthly realm, or the universe at large.
