Word origin
Three uses of 'can' from two roots: the modal verb ('be able to') and the regular verb ('to preserve in a sealed container') both come from Old English cunnan ('to know how to, be able to'), which through specialization became a modal. The noun ('container') is from Old English canne, of Germanic origin, originally meaning a small drinking vessel.
Fun fact
The famous 'How much wood would a woodchuck chuck' tongue twister has a 'can'-based cousin: the canner sentence above is a classic of recursive English wordplay, exploiting that 'can' carries both ability and the literal action of canning.
