Word of the Day:

: gay, merry

"… I had washed my being in the sunrise and felt as blithesome as the day." — Lucy Maud Montgomery, "A Correspondence and a Climax," 1905

"I remember a time when I could waltz directly through the double doors that lead to my children, but those blithesome days have passed." — Christine Cooper, The Morning News (Florence, South Carolina), 17 Dec. 2014

Blithesome comes from blithe, a word that has been a part of English since before the 12th century. Blithe can mean "casual" and "heedless" as well as "joyful" and "lighthearted," but blithesome makes use of only the "joyful, lighthearted" sense. Blithesome didn't show up in print in English until the late 16th century, and is now relatively uncommon; you're most likely to come across it in literary contexts like the one in our first quote. In addition to L. M. Montgomery, such authors as Charles Dickens, Sir Walter Scott, Mark Twain, and Herman Melville found it useful.
