Etymological (Post) Method
o Webster defines it as the history of a linguistic form (such as a word) shown by
             tracing its development since its earliest recorded occurrence in the language
             where it is found, by tracing its transmission from one language to another, by
             analyzing it into its component parts, by identifying its cognates in other
             languages, or by tracing it and its cognates to a common ancestral form in an
             ancestral language
           o With this method, we are only concerned with a word’s later development of
             meanings from the original meaning.
