What is the origin of Hello ?


According to the Oxford English Dictionary, hello is an alteration of hallo, hollo,[1] which came from Old High German "halâ, holâ, emphatic imperative of halôn, holôn to fetch, used especially in hailing a ferryman".[5] It also connects the development of hello to the influence of an earlier form, holla, whose origin is in the French holà (roughly, 'whoa there!', from French là 'there')
