Thing Not To Be Today: glaikit.

(You say this word GLAY-kit.)

Here's a lovely Scottish word (though it's been used in Ulster and the North of England, too).

I can't pretend there aren't alternative words for glaikit, but there are so many occasions for its use that one more can only be a good thing. 

You can say it with such energetic contempt, too.

Glaikit means stupid, foolish, witless, or thoughtless.

It might prove useful to have such a word that no one's near you is going to understand.

Or it might have its uses when coming across dangerous driving in the car. 

Especially if the children are listening.

Thing Not To Be Today: glaikit. The Scots word glaiks means pranks, and that word probably came from the Middle English gleek, a jest or trick.
