Etymology

Etymology is the scientific study of the origin and evolution of a word's semantic meaning across time, including its constituent morphemes and phonemes.

Quote on etymology:

 * Etymology? All the words come from that first howl. (Stanisław Jerzy Lec)
 * Etymology is the psychology of language, the way of penetrating the soul of words. An etymological mind derives infinite enjoyments from words, which are ignored by those who consider words only as conventional sounds; just as a psychological mind derives infinite enjoyment from the association with men, who are ignored by those who consider man only as a speaking and self-propelled form. (Alberto Savinio)
 * A man who cultivates his garden, as Voltaire wanted. | Who is happy that music exists on earth. | Whoever discovers an etymology with pleasure. | [...] | Such people, who ignore each other, are saving the world. (Jorge Luis Borges)
