   Format: MarkdownItexIt doesn't really matter, but I'm not convinced by the "common theme" sentence... . Surely the point is more like that it describes something which cannot be counted?

   Format: MarkdownItexMostly it means something larger than every natural number, although not always. I put a sentence saying that and noting a couple of exceptions (one each way). You could still argue (even with those exceptions) that it means something larger than whatever can be counted, for some sense of counting.

   Format: MarkdownItex"Larger than" or "beyond". I don't think of ordinary real numbers as things one counts, but when thinking about calculus, I do think of $\infty$ and $-\infty$ as ideal points beyond all finite real numbers. Similarly with valuation fields, etc.
