Here’s a good Vietnamese word I ran across recently. Just make note that I hadn’t all the proper accent characters for some of the letters. For instance the ‘d’ in dô should have that line that crosses over the top portion. If you’re familiar with Vietnamese at all you’ll know what I’m talking about. If not, this is great opportunity to get familiar with the lang!
