National Jack Day

The Name That Became a Word. Jack's dominance had linguistic consequences. By the mid-14th century, it had crossed from a proper name into a generic noun meaning "any man," especially a laborer or commoner. This shift produced an entire family of English compound words: lumberjack, steeplejack, flapjack, crackerjack, and the phrase"jack of all trades,"which first appeared in the early 17th century as a compliment before later acquiring its dismissive second half.The name also saturated English folklore. Jack and the Beanstalk, Jack the Giant Killer, Jack Sprat, Little Jack Horner, and Jack and Jill all drew on the name's everyman associations, using an ordinary-sounding protagonist to anchor extraordinary stories. By the time Joseph Jacobs published his definitive English Fairy Tales collection in 1890, Jack had appeared in more folk narratives than any other English name
