addle

obsolete Someone who is stupid or foolish. Mother wants to arrange a marriage between George and myself, but I know I would be completely miserable married to an addle pate like him. I am not surprised to hear that an addle pate like him has already squandered his inheritance. Watch what you're doing, you addle pate—you nearly broke the machine!

Confused, bewildered, or disoriented. This cold medicine has left me totally addlebrained—I just wrote down that 2 + 2 = 5. Get used to feeling addlebrained—that's just part of life as a sleep-deprived new mom. I spent an hour searching for that file, and it was right under my nose the whole time. Boy, am I addlebrained today!

obsolete One who disrupts or interferes with someone else's plans or enjoyment. If you want to have a good time, we can't invite that addle-plot. Father won't let us take the horses out today? What an addle-plot. Margaret's coming for a stay, and I really hope she doesn't bring her husband, the addle-plot, along.
