The fact that a term is labelled with any one of theses does not necessarily mean its use is confined to that culture. In particular, many terms labelled MIT and Stanford are in quite general use. We have tried to give some indication of the distribution of speakers in the usage notes; however, a number of factors mentioned in the introduction conspire to make these indications less definite than might be desirable. A few new definitions attached to entries are marked [proposed]. These are usually generalizations suggested by editors or Usenet respondents in the process of commenting on previous definitions of those entries. These are not represented as established jargon.
