Usage

Terms and definitions labeled Obsolete in this dictionary have not been in widespread use since the mid 1700s. Unlike some relatively familiar archaic words and phrases, like prithee and thou art, obsolete words and phrases are not easily understood by a modern reader, and obsolete senses of current terms, as found in definitions 13, 14, and 15 of nice, are even more difficult for a contemporary reader to recognize.

The word obsoleteness is hardly ever used, obsolescence standing as the noun form for both obsolete and obsolescent

Other Word Forms
