“No sugar” or “sugar-free” in Chinese is 无糖. The character 无, in its simplified form (not 無), is not particularly difficult to write. It’s barely more complex than “#.” The character for “sugar,” however, is a different story: 糖. Kind of complex.
So if you’re working in a coffee shop and have to quickly mark coffee cups with a label that means “no sugar,” what are you going to use? Are you going to bother to write 无糖 over and over? Here’s what an employee at Knight Coffee writes:
So “无t” instead of “无糖.” (You can often see similar things going on if you can get a peek at the way that restaurant servers write down food orders by hand.)
Modern Chinese people grow up being equally familiar with the Latin alphabet and Chinese characters. Writing by hand is becoming less and important, and writing characters is sometimes seen as a burden. Typing on a computer can make it easier to type out complex characters (because you’re not actually writing out all the strokes anymore), and yet young Chinese people on the internet are mixing the Latin alphabet into Chinese quite liberally.
It does make you wonder how quickly we’re going to start seeing fundamental changes to the way Chinese people write. All languages change over time, although the written language often resists change much longer. But there’s a new catalyst in the equation this time: the internet.
