The story of the word

ἀμφίβιος describes a creature at home in two elements. Greek writers also used it of people leading a double existence, a sense English briefly kept in the 17th century before biology took the word over. The military meaning, an assault launched from ships onto a defended beach, is a 20th-century development that would have baffled Aristotle.
