In the codebase where I encountered this convention, the `a` prefix did not refer to the _word_ "a" (indefinite article), but rather was an abbreviation for "argument" (used as an imprecise synonym for "parameter"). So, with this convention, the prefix would be `a` even in front of `Apple`.

But I suppose I can imagine a different convention where the prefix is an indefinite article and so you'd get `anApple`.
