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!

Pronunciation: /ɑ:rˈkeɪɪk/
English description: so extremely old as seeming to belong to an earlier period
Synonyms: antiquated
Chinese Translation: 古代的(gu3 dai4 de)
Spanish Translation: arcaico
ORIGIN: 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 It can also mean something that is outdated but can still be found in the present and therefore could seem out of place.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.

EXAMPLE SENTENCE:

Baseball players and a segment of the baseball media see themselves as keepers of some archaic flame that exists outside the purview of umpires.
