AVATARとは 意味・読み方・使い方

• avatara (rare)

語源

First use appears c. 1784, in The Hindu Wife; or, The Enchanted Fruit, by William Jones. Borrowed from Hindustani अवतार / اوتار (avtār), from Sanskrit अवतार (avatāra, “descent of a deity from a heaven”), a compound of अव (ava, “off, away, down”) and the vṛddhi-stem of the root √तॄ (√tṝ, “to cross”).

In the computing sense, some use appeared in video games in the 1980s, such as the online roleplaying game Habitat (1985) by Lucasfilm Games (today LucasArts), by Chip Morningstar and Randy Farmer, later versions of the Ultima series (following religious use in Ultima IV: Quest of the Avatar (1985)), and the pen and paper role-playing game Shadowrun (1989). Also popularized by the novel Snow Crash (1992) by Neal Stephenson.
