Etymology: Middle English germain, having the same parents; closely connected, from Old French, from Latin germanus, from germen, offshoot.
"Osric: The carriages, sir, are the hangers.
Hamlet: The phrase would be more german to the matter, if we
could carry cannon by our sides: I would it might
be hangers till then. But, on: six Barbary horses
against six French swords, their assigns, and three
liberal-conceited carriages; that's the French bet
against the Danish. Why is this 'imponed,' as you call it?" (Hamlet, William Shakespeare, ~1600).
