Fleming, if we are restored to our throne, shall we not have one blithesome day at a blithesome bridal, of which we must now name neither the bride nor the bridegroom?
-- Sir Walter Scott, The Monastery, 1820
Why had she never noticed before how blithesome the world was, how jocund with love; the birds sang it, the trees whispered it to her as she passed, the very flowers beneath her feet strewed the way as for a bridal march.
-- Mark Twain and Charles Dudley Warner, The Gilded Age, 1873
Blithesome entered English in the early 1700s from the Gothic term bleiths meaning "kind, merciful."
