I always thought those whoe said susa instead of soos are wrong.
Suse stands for “Software und System-Entwicklung” https://linuxiac.com/opensuse/
Edit: Yes, she can still be wrong but then it’s supported by the rest of susa’s staff https://youtu.be/RsME20zXbQI&t=13
So what’s the deal with GNU? When I first saw it, I was sure the G was silent, or formed a dipthong, like gnat or gnocchi or gnaw or gnarly or gnome or just any word starting with gn in English. But IRL, I’ve only heard it pronounced with a hard G, same with Gnome.
Well thats the thing, generally if I see an acronym and have to ask myself how it would be pronounced as a word, by my rule I just spell it out.
For a great example of this (unrelated to FOSS), look at LGBTQIA+. Even though it’s a mouthful to say each letter individually, no one wrestles it into “Leguhbuht’kwia plus”, it just doesn’t make sense and saying it that way would probably ellicit a dead stare from whoever heard it. Unless it’s painfully simple to morph into a word or single syllable, I don’t bother.
I’m not trying to say this is the right way, mind you. It’s just the way that makes the most sense to me.
Except GNU is a great example of an acronym that is pronounceable. It’s even in the dictionary. The GNU mascot is a gnu, in fact.
LGBTQIA+ is essentially unpronounceable, thus we treat it as an initialism. Not that that’s a requirement, there are examples like VIP where even though we could pronounce it we pronounce each letter individually.
