Earlier uses can be found back to 1849 and 1846:
It was listed in dictionaries by 1883.
The word was extensively used in literature by the 1860s. Two early uses of hello can be found as far back as 1826.
By 1889, central telephone exchange operators were known as 'hello-girls' due to the association between the greeting and the telephone.
It was in use in both senses by the time Tom Brown's Schooldays was published in 1857 (although the book was set in the 1830s so it may have been in use by then):
Although much less common than it used to be, the word hullo is still in use, mainly in British English.
Webster's dictionary from 1913 traces the etymology of holloa to the Old English halow and suggests: "Perhaps from ah + lo; compare Anglo Saxon ealā."
According to the American Heritage Dictionary, hallo is a modification of the obsolete holla (stop!), perhaps from Old French hola (ho, ho! + la, there, from Latin illac, that way). Hallo is also used by many famous authors like Enid Blyton. Example:"Hallo!", chorused the 600 children.
The Old English verb, hǽlan (1. wv/t1b 1 to heal, cure, save; greet, salute; gehǽl! Hosanna!), may be the ultimate origin of the word. Hǽlan is likely a cognate of German Heil and other similar words of Germanic origin.
Of course, in many other nations "hello" is no longer considered foreign, as evidenced by the number of people that have adopted it into their own language (as in French âllo).
