----- and the like. [ 1913 Webster ]

The above classes of words are unlimited in extent, and such compounds may be formed by any writer or speaker at will from almost all the adjectives or participles in the language, excepting those which have a recognized and usual negative correspondent with the prefix -in. No attempt will be made, therefore, to define them all in this Dictionary; many will be omitted from its Vocabulary which are negations of the simple word, and are readily explained by prefixing a not to the latter. Derivatives of these words in -ly and -ness will also, for the most part, be omitted for the same or similar reasons. [ 1913 Webster ]

There will be inserted as separate articles with definitions, the following: -- [ 1913 Webster ]

1. Those which have acquired an opposed or contrary, instead of a merely negative, meaning; as, unfriendly, ungraceful, unpalatable, unquiet, and the like; or else an intensive sense more than a prefixed not would express; as, unending, unparalleled, undisciplined, undoubted, unsafe, and the like. [ 1913 Webster ]

2. Those which have the value of independent words, inasmuch as the simple words are either not used at all, or are rarely, or at least much less frequently, used; as, unavoidable, unconscionable, undeniable, unspeakable, unprecedented, unruly, and the like; or inasmuch as they are used in a different sense from the usual meaning of the primitive, or especially in one of the significations of the latter; as, unaccountable, unalloyed, unbelieving, unpretending, unreserved, and the like; or inasmuch as they are so frequently and familiarly used that they are hardly felt to be of negative origin; as, uncertain, uneven, and the like. [ 1913 Webster ]

3. Those which are anomalous, provincial, or, for some other reason, not desirable to be used, and are so indicated; as, unpure for impure, unsatisfaction for dissatisfaction, unexpressible for inexpressible, and the like. [ 1913 Webster ]

II. Un- is prefixed to nouns to express the absence of, or the contrary of, that which the noun signifies; as, unbelief, unfaith, unhealth, unrest, untruth, and the like. [ 1913 Webster ]

☞ Compounds of this last class are given in full in their proper order in the Vocabulary. [ 1913 Webster ]
