If your friends and family enjoy belting out a yule tide tune as much as mine do then you're probably quite familiar with Christmas songs like It Came Upon A Midnight Clear, Jingle Bells and Deck The Halls.
And even though we know all the words and sing these songs and more during Christmastime every year the lyrics contain certain archaic words and phrases that leave us wondering what the hell the songwriters were talking about.
"Bells on bobtail ring?" That refers to a horse's tail that has been cut short, which bells were sometimes hung on for decoration.
"Troll the ancient yuletide carol?" That doesn't mean carolers were going around trolling people all over town, it means they were singing loudly and clearly so all could hear.
"Still through the cloven skies they come?" This doesn't refer to a cloven-hooved cow angel descending from heaven, it means the clouds have cloven (parted or split) so the angels can come down and sing. Regular humanoid angels, not mooing cow angels with teats a-flutter, although that would be way cooler.
