I would be so afraid to do this! And yet so enthusiastic. *dies* Aria, one day, we'll stop deconstructing you.

According to Wiki and vague Pinker memories, the 'tense' would probably a different way of expressing modality than just mood, since it's more than just possibility, but yeah, sure. It could also be an aspect? Since the concept of perpetuation is so intrinsic?

Wiki also informs me, semiobviously, that all of these borders are fuzzy in English, which is why we are bad at understanding it. Perhaps High Gallifreyan does not have the same classification system as Earth language, and so tense is the easiest conflation.

PS JI I WAS AT A PARTY ;_;
