1784, “descent of a Hindu deity,” from Sanskrit avatarana “descent” (of a deity to the earth in incarnate form), from ava- “down” + base of tarati “(he) crosses over,” from PIE root *tere- “to cross over” (see through). In computer use, it seems to trace to the novel “Snowcrash” (1992) by Neal Stephenson.
avatar [(av-uh-tahr)]

In Hinduism, a god made visibly present, especially in a human form. The Buddha is considered an avatar of the god Vishnu.

Note: By extension, an “avatar” is any new embodiment of an old idea.

1. An image representing a user in a multi-user virtual reality (or VR-like, in the case of Palace) space.
2. (CMU, Tektronix) root, superuser. There are quite a few Unix computers on which the name of the superuser account is “avatar” rather than “root”. This quirk was originated by a CMU hacker who disliked the term “superuser”, and was propagated through an ex-CMU hacker at Tektronix.
