What is Etymology?

The word nature means the universe, with all its phenomena.[6] Natura was a Latin translation of the Greek word physis (φύσις), which originally related to the intrinsic characteristics that plants, animals, and other features of the world develop of their own accord.[7] The word φύσις occurs very early in Greek philosophy, generally in similar senses to those of the modern English word nature.[8] This is shown in the first written use of the word φύσις, in connection with a plant by Homer.[9] The concept of nature as a whole, the physical universe, is one of several expansions of the original notion. This usage was confirmed during the advent of modern scientific method. Isaac Newton's Philosophiae Naturalis Principia Mathematica (1687), for example, is translated "Mathematical Principles of Natural Philosophy". The etymology of the word "physical" shows its use as a synonym for "natural" in about the mid-15th century.[10]
