Isn't originalWord really englishWord? Do you translate from other languages? Here, "original" is a structurally-accurate name, but not intention-revealing: it describes the role the parameter plays in implementing the algorithm, but not the role that the information plays in achieving the goal of translating into Pig Latin.

In the case of simplePiglatinWord(), I find this name accurate and vague but imprecise and slightly misleading. I see this method as using the simple English-to-Pig Latin translation method (adding "way" at the end), and so suggest the name translateWithSimpleRule() or translateWithSimpleMethod(). I worry about using the term method in OO code, because of its OO-specific meaning. I might expect reflection code when I see that name. I also thought about translateSimply(), which sounds clever, but the corresponding translateComplexly() sounds weird.

Finally, findFirstVowelIndex() represents another implementation-bound name: in particular, it uses Java's language where I would suggest positionOfFirstVowel(). I see this point less clearly, since we to accept index as a common term in Java.

I have code suggestions, too, but I know you wanted to focus on names here.
