Etymology: "Unearthly" is a compound formation built from the prefix "un-" combined with the adjective "earthly," and its coinage reflects a straightforward but semantically rich process of negation and abstraction that took place in early modern English. The base word "earthly" descends from Old English "eorðlic," formed from "eorðe" (earth) plus the adjectival suffix "-lic" (which survives in modern English as "-ly" in words like "kingly" and "friendly"). The Old English "eorðe" itself comes from Proto-Germanic ""erþō," ultimately tracing back to Proto-Indo-European roots related to ground and soil. By the time of Middle English, "earthly" had become the standard adjective meaning "of or belonging to the earth" or "terrestrial," and it was frequently used in theological and philosophical contexts to denote the material, physical world as opposed to the spiritual or heavenly realm. The prefix "un-" is native to English, inherited from Old English and Proto-Germanic ""un-," and was already a productive tool for negation by the medieval period. The combination "unearthly" appears to have emerged in the 16th century, though the exact date of first attestation is uncertain. The word initially carried the literal sense of "not of the earth" or "not belonging to the earth," but quickly developed the figurative meanings that dominate modern usage: something strange, bizarre, or otherworldly in character; something so unusual or supernatural in quality that it seems to transcend ordinary earthly experience. This semantic evolution reflects a common pattern in English where negation of a concrete, material adjective generates an abstract or evaluative sense. To call something "unearthly" is not merely to deny its earthly origin but to mark it as alien, uncanny, or extraordinary—as if it belongs to a realm beyond normal human perception or experience. The word has proven durable and remains in common use today with much the same meaning it acquired in the early modern period.
