What does archaism mean?
An archaism is a word, phrase, grammatical form, or stylistic practice that has dropped out of everyday use but survives in particular contexts — literature, law, religion, ritual, or deliberate imitation of earlier eras. Examples include expressions like "thou," "wherefore," and "prithee," which sound distinctly old-fashioned to modern ears. The term also covers the intentional revival of such antiquated language: writers from Spenser to Tolkien have employed archaism to lend their work gravity, atmosphere, or a sense of historical depth. In linguistics and literary criticism, distinguishing an archaism from a mere obsolete word matters; an archaism remains in limited, often ceremonial or artistic circulation, while truly obsolete words vanish entirely. The concept is closely tied to its adjective form, "archaic," which describes anything characteristic of an earlier period. For readers and writers alike, recognizing archaisms sharpens awareness of how language evolves and why certain fossilized words continue to resonate long after their practical usefulness has faded.

Etymology of archaism
Archaism derives from the Greek "arkhaios" (ancient), via "arkhē" (beginning), passing into Latin as "archaicus" before entering English in the early 17th century. It shares this Greek root with words such as "archaic," "archaeology," "archive," and "archetype." The word has been used since its adoption to describe both survivals of antiquated language and the conscious imitation of ancient styles.
