- Description: The dictionary covers the current vocabulary of standard written and spoken English. New terms or new uses of existing terms are therefore included at the expense of obsolete ones. The cut-off point is set at 1755 and is informed by usefulness: words obsolete before this time, unless found in the well-known works of major authors, are omitted.
