[Greek arkhaikos, old-fashioned, from arkhaios, ancient, from arkh
, beginning, from arkhein, to begin.]An archaic language is a language that is no longer current or applicable, like latin. It's so extremly old as seeming to belong to an earlier period, like "a ramshackle antediluvian tenemen''.
Archaic: It's old, for long duration, not new. ''Old tradition'', ''old house'', ''old wine'', ''old country'', ''old frienships'', ''old money'', etc.
This highly serrated arrowhead (about one and one-half inches in length) is an example of an artifact from the pre-agricultural Archaic Period.
