Here's is a simplification of the question, below it is why I an unsure where it should go:
Is this a metaphorical or figurative sentence: "His heart was filled with anguish, anger and sorrow".
Is this metaphorical writing, or figurative writing? It isn't really a metaphor, as it isn't translatable to direct speech, right? I think it is figurative, as it isn't using the literal meaning of words, as your actual heart isn't the center for emotion in your body. But I'm not sure. Is it perhaps both?
Now, this question does heavily relate to writing. It is asking a question about metaphors and figurative speech. But it is effectively about the definitions of these things.
So, is this question a Writing SE or EL&U question. Or is it (conceptually) fit for neither? Or is it fit for both? If so, which one would it be best on?
Here's a related question where I ask the same question about a different question, where the conclusion, provided by Cyn, was that the question in question was fit for both sites.
(just wrote question four times in that sentence)
