Did You Know?
As a prefix, arch- appears in a number of titles referring to positions of superiority, such as archduke and archbishop. Ultimately deriving (via Latin and French) from the Greek verb archein ("to begin, rule"), it can also mean "chief " (as in archnemesis) or "extreme" (as in archconservative). In the 17th century, as the "extreme" sense of arch came to be used frequently to describe rogues, knaves, and other clever and mischievous sorts, arch eventually settled into use as an adjective to describe one with impish or playful qualities. Use of the word has since extended to describe actions or remarks meant to be ironic, cutting, or condescending.
