the word 'unearthed' is built upon the old english foundation 'eorþe', which referred to the ground or soil. the addition of the prefix 'un-', a common germanic element denoting reversal, transforms the action of 'earthing' (burying) into its opposite. the suffix '-ed' marks it as a verb in the past tense or past participle form. thus, the literal progression from "to remove from the earth" evolved into the modern abstract meanings of discovering something by digging it up or revealing something that was concealed.

Structure: un (reversal) + earth (ground) + ed (verb suffix) un: a prefix of germanic origin, meaning "not" or "reversal of an action". earth: from old english 'eorþe', meaning "ground, soil, the world". its functional role is the core root. ed: a suffix of old english origin, used to form the past tense and past participle of regular verbs.
