Etymology

Origin of alias

First recorded in 1525–35; from Latin: “at another time, otherwise”; see also else

Explanation

Your alias could be as important as the name you use when you’re on the run or as simple as your screen name on a social networking site. Either way, an alias is a temporary name, one you don’t use all the time or for every occasion. If you crash your parents' lovingly-restored sports car into the garage when you aren't even supposed to be driving it, it might be easier to skip town and live under an assumed name, or alias, than deal with their reaction. Alias can also be used as an adverb to mean "also known as." Your parents might be less than thrilled when you introduce your new boyfriend, "John Smith, alias Lock-Jaw Johnnie, wanted in 39 states."
