Coming directly from Scottish, our word of the day’s origin isn’t clear, although some believe it’s derived from the word ‘unkenned,’ which means ‘unknown.’ Here’s an example of unco in use:

During my trip to Spain, I found myself in a number of unco settings. Thankfully though, my Spanish was good enough to help me navigate back to the hotel whenever I got lost.
