Etymology
The compound adjective 'self-taught' is a transparent formation from core Germanic elements. 'Self', with roots in Proto-Germanic selbaz, carries the enduring sense of identity and agency. 'Taught' originates from the Old English verb 'tǣcan', which itself derives from a Proto-Germanic root meaning "to show". The literal combination, "taught by oneself", directly reflects the modern abstract meaning. This logic of auto-didacticism is common in Germanic languages, where compounding clearly expresses the means of acquisition, contrasting with Latinate forms like 'autodidact'.
Analysis
Structure: self (own) + taught (instructed)
self: From Old English 'self', 'seolf', 'sylf', meaning "own, same". A Germanic root functioning as a reflexive pronoun or prefix indicating the subject's own action or state.
taught: The past participle form of the verb 'teach', from Old English 'tǣcan' (to show, point out, instruct). It functions here as the passive/resultative element, meaning "having been instructed".
