Polish is a language from another world. However in this case it’s way simpler. Linux is just … Linux. If we have a letter we speak a and not ey or anything else. 
That’s said there is no x letter in Polish, so we spoke it using Polish letters instead. iks when speaking x separately and just ks in any other case, so taxi is simply spoken as taksi or taksówka as a Polish word with a taxi origin. 
I always have trouble speaking for example API, because I’m automatically speak it in Polish way instead of ey-pi-ay as it’s terribly not-intuitive for us to speak each character separately (there are of course similar cases in slang, but it was much more popular when SMS messages were expensive and people were forced to “shorten” their texts). 
I heard that most people have problems with inflecting (?) words in Polish language (like plural version). For example I heard story about one tourist who said that Poles really likes dogs, because there are even signs to be aware of them crossing the street. The problem of it is that he made a mistake in pluralization. 
pies(dog - singular) →psy(plural version - similar change likemouse→mice)
pieszy(pedestrian - singular) →piesi(plural version - similar change likey→ies)
So a sign with text Uwaga piesi does not mean Beaware dogs, but Beaware pedestrians. Well … I’m not surprised that people call it the world’s hardest language.
