I’m noticing that most of my kids books have three approaches to the latter X:
- Use “Xylophone” or “X-ray”
- Use something utterly insane like “Xoloitzcuintli” (I dare you to try and pronounce it)
- Ignore it:
The ignore it option is obviously not ideal, in fact there is a great 3 letter word starting with x, “Xis”, which is the 14th letter of the Greek alphabet (which means you can then explain to your kids that there are other languages, and some are root languages and so on, a teachable moment!).
