The Full Story
Latin15th century (English adoption)well-attested
'Fragile' derives from Latin 'fragilis' meaning 'easily broken, brittle, frail,' formed from the root 'frangere' meaning 'to break.' The Latin adjective 'fragilis' is directly attested in classical authorsincluding Cicero and Ovid, where it described physical breakability as well as vulnerability more broadly. English adopted 'fragile' directly from Latin in the mid-15th century, with early attestations appearing around the 1560s–1570s in texts dealing
Did you know?
'Fragile' and 'frail' are doublets — the same Latin word, *fragilis*, borrowed into English twice by different routes. 'Frail' came through Old French, which eroded the Latin form; 'fragile' was borrowed directly from classical Latin centurieslater. They started identical and drifted apart, now occupying different humanterritories
.' This PIE root is reconstructed by comparative linguists including Pokorny (IEW p. 165) and is well-attested across the Indo-European family. In Latin, *bhreg- yielded 'frangere' (to break) via regular sound change, which spawned a rich word family: 'fractus' (broken, past participle → English 'fracture,' 'fraction,' 'infraction'), 'fragmentum' (a broken piece → English 'fragment'), and 'naufragium' (shipwreck, from 'navis' + 'frangere'). In Germanic languages, the same PIE root *bhreg- produced Old English 'brecan' (to break) → Modern English 'break,' as well as 'breach.' In Gothic it appears as 'brikan.' The semantic range of *bhreg- was consistently physical fracturing, and most descendants retain this core sense. The shift from purely physical breakability to metaphorical fragility (emotional sensitivity, institutional weakness) occurred progressively in English use from the 17th century onward, reflecting broader semantic broadening patterns common in adjectives of vulnerability. Key roots: *bhreg- (Proto-Indo-European: "to break"), frangere (Latin: "to break, shatter"), fragilis (Latin: "easily broken, brittle").
