Words of general use will be known by having no sign of particularity,

The words appropriated to poetry will be distinguished by some mark
prefixed, or will be known by having no authorities but those of poets.

Of antiquated or obsolete words, none will be inserted, but such as are

disgrace.

The words which are found only in particular books, will be known by the
single name of him that has used them; but such will be omitted, unless
either their propriety, elegance or force, or the reputation of their
authors, affords some extraordinary reason for their reception.
