Brought to you by the makers of caffeinated coffee and toasted bagels, here's the Tuesday Test Time challenge at the mentalfloss.com Brain Game. Good luck!
List all the non-obscure four-letter English words you can (I found six) that contain the letter-sequence: UA
Here is the LIST.
AQUA, DUAL, LUAU, QUAD, QUAY, YUAN.
I also found "quag" in some dictionaries, but not often enough to warrant a spot on the list. If you found any other four-letter words that fit the pattern (that you consider non-obscure English words) feel free to add them in the comments. Thanks!
