*Also sometimes there are other factors under consideration when
  definitions are produced. Some definitions come from usage. Some
  come from fine-tuning based upon the particular needs of a
  subculture.

  In one subculture, a glossary will have a precise set of
  definitions that work within their subculture.

  Another subculture may operate from a different glossary that
  utilizes the same words but utilizes other meanings that may
  differ.

  It's not that either side is more right or wrong, but "speaking
  the same language" is critical in negotiating meaning.
