Root Breakdown

=archaic

archae- (ancient) + -ic (having the nature of) = "having the nature of the ancient." From naming the old, the word grew a judgment: something archaic isn't just old, it feels out of place today — an archaic law, an archaic word.

Usage Guide

Tone varies. Neutral/technical: linguists call old grammar "archaic" without criticism (thou, thee). Mildly critical: calling a system or attitude "archaic" implies it should have been replaced long ago. In dictionaries, the label archaic marks a word as no longer in normal use.

Example Sentences

  • 1.

    The contract still uses archaic legal language no one understands.

  • 2.

    "Thou" is an archaic form of "you."

  • 3.

    Critics called the company's hierarchy hopelessly archaic.

Easily Confused

archaic vs obsolete — Both mean out of date, but degree differs. Archaic is old-fashioned yet still understood and occasionally used (poetry, law). Obsolete is fully dead — no longer used or functional at all (an obsolete machine, an obsolete word dropped from the language). Still around but quaint → archaic; gone for good → obsolete.

Synonym Comparison

- archaic — old-fashioned, from an earlier era, but still recognizable

- ancient — extremely old, from the distant past (ancient Rome)

- obsolete — no longer used or produced; replaced by something newer

- antiquated — outdated and impractical, often with a tone of disapproval

- old-fashioned — neutral, everyday word for out of current style
