"All" is used instead of "many" metaphorically, "all" being a species of "many." [Note] And again, "Alone unsharing " [Note] is metaphorical; the best known is called the only one.
By intonation also; for example, the solutions of Hippias of Thasos, his " δίδομεν δέ οἱ" [Note] and τὸ μὲν οὗ καταπύθεται ὄμβρῳ [Note];
and by punctuation; for example, the lines of Empedocles: Soon mortal grow they that aforetime learnt Immortal ways, and pure erstwhile commingled. [Note]

Others according to the habitual use of the phrase, e.g. wine and water is called "wine" so you get the phrase "greaves of new-wrought tin"; [Note] or workers in iron are called "braziers," and so Ganymede is said to pour wine for Zeus, though they do not drink wine. This last might however be metaphorical. [Note]
