• (psychology) According to Swiss psychologist Carl Jung: a universal pattern of thought, present in an individual's unconscious, inherited from the past collective experience of humanity.
  "The three archetypes so far discussed—the shadow, the anima, and the wise old man—are of a kind that can be directly experienced in personified form. In the foregoing I tried to indicate the general psychological conditions in which such an experience arises. But what I conveyed were only abstract generalizations. One could, or rather should, really give a description of the process as it occurs in immediate experience. In the course of this process the archetypes appear as active personalities in dreams and fantasies."
• (textual criticism) A protograph (“original manuscript of a text from which all further copies derive”).
