Etymology

Hello (first attested in 1826), from holla, hollo (attested 1588). This variant of hallo is often credited to Thomas Edison as a coinage for telephone use, but its appearance in print predates the invention of the telephone by several decades. Ultimately from a variant of Old English ēalā, such as hēlā, which was used colloquially at the time similarly to how hey and (in some dialects) hi are used nowadays. Thus, equivalent to a compound of hey and lo. Used when drawing attention to yourself. Possibly influenced by Old Saxon halo!, imperative of halōn (“to call, fetch”), used in hailing a ferryman, akin to Old High German hala, hola!, imperative forms of halōn, holōn (“to fetch”). More at hallo. OED and Merriam-Webster also suggested that it is a variant of holla, a variant of holloo. Further beyond, the origin remains uncertain. OED and Merriam-Webster suggested that it has a connection between hallow (“to shout, to cry out loud”), which came from Old French holloer, which, according to Altfranzösisches Wörterbuch, is from Old Saxon halōn.
