Thanks.
I'm afraid I didn't understand how to pronounce "codomain" though. Is the main stress on the first syllable? -->
Coh-doh-main
Also, there are a lot of words I have trouble with... And that happens every time I come across a word that can be pronunced in many different ways. For example "Pythagorean theorem": M-W says the stress is on Pythago
rean, but I always heard Py
thagorean in several videos. Or cases like "obtuse", which can be pronounced in two different ways according to M-W, but I don't know which one to choose...
