>>29126369Many pokemon names fuck with conventional english grammar rules anyways. Quite a few have more than one stressed syllable, among other things, and in english an exception exists for almost anything.
However, following English linguistic trends, a C followed by an "e" is most commonly a soft C, or S. Examples include words like Decent, Licence, Recent, or Recess. There are mid-word C's that use a hard C, but these almost always precede other vowels, like in Decanter.
Now, the real puzzle comes from where the syllable break is. If the syllables are "Ar-ce-us" than it would make more sense as a soft C. If the syllable break were "ark-e-us", then a hard C would be more appropriate. "RKS" however gives us a more stylized pronunciation of "Ar-Kay-Es, in an attempt to match the abbreviation. Again, "Ar-ce-us" would be the most likely syllable break (though by a less beefy margin of certainty than Ce=soft C).The problem comes from the fact that proper names, and Pokemon in particular are prone to screw with common pronunciation to make a name mean something different. Off the top of my head, "Ark-e-us" could be attempting to reference Noah's Ark, or the Ark of the Covenant. Arceus has no particular relation to these items, but the reference could serve the purpose of making it seem more divine and, remember this is a Japanese series, exotic.
English has enough exceptions, even before considering the fact that Pokemon makes exceptions far more frequently than average, that I would say to take this with a grain or two of salt. Whatever Pokemon says wins out in the end. However, linguistically speaking, without accounting for context, referencing, or screwy Pokemon pronounciation in general, if I saw Arceus having never seen it efore, I would assume it was pronounced "Ar-see-us".
As of "RKS system though, I believe it more likely to be pronounced "Ar-Kay-Ehs". No I don't like it.
