Cutty-sark
I’ve long known about the whisky called Cutty Sark, and I vaguely knew that it was named after a ship.
But I didn’t know until today that the ship was named after a fictional character’s nickname:
The ship was named after Cutty-sark, the nickname of the witch Nannie Dee in Robert Burns’s 1791 poem Tam o’ Shanter. […] In the poem she wore a linen sark (Scots: a short chemise or undergarment), that she had been given as a child, which explains why it was cutty, or in other words far too short. The erotic sight of her dancing in such a short undergarment caused Tam to cry out “Weel done, Cutty-sark”, which subsequently became a well known catchphrase.
