borscht, "trial" is (and has been for a while) a totally legitimate verb.

"t says "vowel-heavy language," not "vowel-heavy alphabet."

This it is a very unclear comment. To the extent an alphabet is a written representation of a language, the alphabet should contain all of the vowels present in the language, so they mean the same thing. Vowels in any language have to be pronounced carefully, whether they are split by consonants or not. A simple look at all the dialects of English present in the world today should be more than enough to debunk this ridiculous theory, as the main difference between spoken Englishes is the pronunciation of the vowels. The total number of times vowels appear in a sentence aside, Japanese still only has five vowels to process. Of course, you can lengthen an utterance, but so can any language.
