Here's a question. How come maintain, maintained, maintaining and maintainable have an "ai" at the end, but maintenance just has an "e"? I'm constantly spelling it maintainence. Is it just so spell checkers can mock me each time I spell it wrong?
And before anyone says "because you don't say it that way", since when has the spelling of a word in English got in the way of its pronunciation? Sheesh, what a bunch of knights.
Our language is weird, I maintain.
