History of Uncouth: From Unfamiliar to Outlandish

Old English speakers used the word cūth to describe things that were familiar to them, and uncūth for the strange and mysterious. These words passed through Middle English into modern English with different spellings but the same meanings. While couth eventually dropped out of use, uncouth soldiered on. In Captain Singleton by English novelist Daniel Defoe, for example, the author refers to “a strange noise more uncouth than any they had ever heard,” while Shakespeare wrote of an “uncouth forest” in As You Like It. This “unfamiliar” sense of uncouth, however, joined couth in becoming, well, unfamiliar to most English users, giving way to the now-common meanings, “rude” and “lacking polish or grace.” The adjective couth in use today, meaning “sophisticated” or “polished,” arose at the turn of the 20th century, not from the earlier couth, but as a back-formation of uncouth, joining the ranks of other “uncommon opposites” such as kempt and gruntled.
