Blunderbuss

Blunderbuss is an adjective that means a frequently blundering person. Our word of the day sometimes refers to a firearm with a short muzzle. The word is derived from the Dutch word for ‘thunder.’ But blunderbuss can also refer to a person prone to many blunders, for example: I don't think it’s such a good idea to leave Tim in charge of the cash register this weekend. Knowing what a blunderbuss he can be, there’s a chance the till will be way off.
