It's twelfth night, a time for taking down the decorations, telling yourself that you really should get round to reading some more of Shakespeare's plays, and, in the past, a lot of jolly role-swapping (this last surely due for an ultra-fashionable revival).
However you celebrate, good luck with sounding all the consonants of the word twelfth.
Word Not To Say Very Distinctly Today: twelfth. The Old English form of this word was twelfta.
Those Old English were no fools, you know.
