Not to me, but to most people.
Using unsubstantiated general terms like 'most people' is a sign of weakness in a debate.
And it isn't changing the name, just the pronunciation.
It's changing the spelling and the pronunciation... that's changing the name, you know.
The whole point of it's name is that "X" represents the cross between light and darkness.
Okay! So you are going to call it the cross-blade, then? Cause "X" doesn't necessarily mean [ɛks] you know.
It being "Ex" in the NA version would make sense to a much more amount of people who play the game, who are mainly kids (who have a reason to not be smart enough to understand, ie. they're young), and those who grew up with the series.
What it sounds like you're saying is, North Americans aren't smart enough to learn one simple cool fact about greek letters?
Anyway, this is what wiki says on the matter.
Chi (uppercase Χ, lowercase χ; Greek: χῖ) is the 22nd letter of the Greek alphabet, pronounced as /ˈkaɪ/ in English. Its value in Ancient Greek was an aspirated velar stop /kʰ/ (in the Western Greek alphabet: /ks/).
Do you know how to read [kaɪ]? That's [k] as in key, and [aɪ] as in pie. So maybe, it's more like Kai-blade. Except that [kaɪ] is actually what you call the letter, it seems. Like how we would call K 'kay', or M 'emm' or W 'double-yew'.
It says it is an aspirated velar stop, which means *digs up phonology textbook* you raise the back of your tongue on the soft back part of your mouth, and then kind of, spit out some cut off air. I think. (I fcuking hate phonology). In any case, it says there on wiki that it's pronounced [ks].... which is like, the sound at the end of 'asks'.
You know, that sounds a hell of a lot like 'X' to me anyway. Ks. Eks. MAYBE IT WILL BE THE 'KS-BLADE.
Edit:
From random greek thingy site
Ancient Greek letter chi was pronounced as [kh] ([k] aspirated, nearly as in English cut) at least until the 2nd century BCE. Its pronunciation started shifting to fricative [x] (i.e., to its Modern Greek pronunciation, which is as in Gernam "Bach") in various places at different times.
Well, it's definitely going to sound more like Key than Cheese or something ;D
