ok ok it’s off-topic and I am sorry…
Ooohhhhhhhh this is interesting.
TIL there are two spellings for one element on the periodic table. Thanks! This solves a long mystery to me. Ye gods, why didn’t I think to look up the word in a British-English lexicon? 
One parent: Shanghainese, Putonghua and Mandarin (primary), with American English as a second language. Scientific Russian and scientific German distant thirds. He may have had some Taiwanese (at the time of his learning it, it would have been called Formosan) but if he did, I can’t say how much.
Other parent: Bavarian-German, Swabian-German, Hochdeutsch (primary), with American English, Italian, French, Brazilian-Portugese, Russian as second languages, and Putonghua as a distant third. She was fluent in everything except for Putonghua though she tried for decades, bless her.
Shortwave radio was played often in our house with all kinds of languages on those cloth-covered speakers, and I used to think everyone listened to it at their houses. Turns out, nope!
Back on topic!
