Haven't done Scots Wurd o' the' day for ages, as I mislaid my Chambers's Scots Dictionary. But now I've found it again.
Today's Scots wurd is "dornicle". It's a noun, apparently. The definition given is as follows: "the viviparous blenny".
I'll be honest - I'm none the wiser, and I can't be bothered Googling it at the moment. Might have a look later on.
