Usage

Archaic is used as a label in this dictionary for terms and definitions that were current roughly as late as 1900 but are now employed only as conscious archaisms, as described and exemplified in definition 2 above. An archaic term is generally more recognizable, as when encountered in literature, than one labeled Obsolete.

Etymology

Origin of archaic

First recorded in 1825–35; from French archaïque, or directly from Greek archaïkós “antiquated, old-fashioned,” equivalent to archaî(os) “old” + -ikos adjective suffix; see origin at -ic

Explanation

If you use the adjective archaic you are referring to something outmoded, belonging to an earlier period. Rotary phones and cassette players already seem so archaic! The adjective archaic means something that belongs to an earlier or antiquated time. It can also mean something that is outdated but can still be found in the present and therefore could seem out of place. The word comes from archaic (i.e., ancient) Greek, archaikos, and literally means "from Classical Greek culture," though its meaning has broadened as it's been used in English.
