Or rather from the "words have a meaning consisting of the combined meanings of their root words, or in the case of compound words, the combined meanings of their constituent words" - summarized as the "silly" point of view.

You don't break a fast anyway, it's a metaphor. You can only break physical things. You interrupt it. Wait, that just means between + break in Latin. That doesn't even make sense - you're ending the fast, not pausing it... but wait, aren't you pausing it - because eventually you'll cease eating. Maybe all words are just convenient labels using metaphors to help us remember them. Anarchy!

edit: I thought about it a little longer, and wondered if "end" might be a better word, then realized that was a physical metaphor too. I've finally settled on a word that makes strict sense: "terminate." From now on, the appropriate word for the first meal you eat after not eating, no matter the time of day or even whether there was a period during that time when you were sleeping (hence every single meal and every single snack) will be "fastermination." And you shouldn't look at me weirdly when I say that; I'm just using English (or Latin or whatever) properly, and in the grand scheme of things, I'm more right than you are.
