Good, because when we were asked about Sofia earlier, I was really stressed about the lack of resolution. I'm glad we can put this to rest now.
Is there a reason we see the name Sofia to the exclusion of all other female names?
You see Sofia and Adam as recurrent names because these were the names of LL Zamenhof's children. Zamenhof is the inventor of the Esperanto language. It's a nice easter egg!
Poor Lidia gets no mention though (at least not in the first third of the course).
When I used "sxia" it called it a typo, I have no other way of typing the letter for /ʃ/
If you are on a computer, there are buttons to write those letters; if you are on mobile, try holding the keys
Doesn't work for most keyboards on mobile because Esperanto isn't taken into account. If you are lucky, the letters are present in some other language, otherwise, there is only one keyboad (don't remember it's name but I thought it was too crappy)
