Shortened Greeting?


I would like to know of what term "ちゃーす" is the abbreviated version. It
appears to be a greeting. Translation software and my closest dictionary were
of no help.

This is simply こんにちは + a highly reduced です.

(EDIT: I claimed this isn't common in real life speech, but I'll defer to
l'électeur's experience and remove that claim.)
