Pronunciation

  • Classical: [ˈfra.ɡɪ.lɪs][1]
  • Ecclesiastical: [ˈfraː.d͡ʒi.lis][1]

Forms

fragilis (neuter fragile, comparative fragilior); third-declension two-termination adjective[1] The ablative singular is fragilī; the vulgar spelling fragele appears in an inscription.[2]

Etymology

It is from Latin frangō (“to break”) + -ilis,[3][1][2] from Proto-Italic *fragelis according to Wiktionary.[1] De Vaan derives ⟨frangō⟩ from Proto-Italic *frang-, a nasal present Proto-Indo-European *bʰr-n-ǵ- (“to break”), cognate with Gothic 𐌱𐍂𐌹𐌺𐌰𐌽 (brikan, “to break”) and Old High German brehhan (“to break”).[4]

Earliest recorded meaning

The TLL and Köbler date it from Accius,[2][5] who has the superlative;[3] de Vaan gives Lucretius as its first author.[4]

Semantic evolution

Of things it is liable to break, brittle: Virgil's boy could just reach the brittle branches from the ground.[3] Virgil also uses it of laurels that crackle in the fire.[3] It came to be used of what is weak or frail, as Horace's frail boat entrusted to a savage sea, of the mind and of the frail years of age.[3] Of circumstances it is unsure and passing: Cicero says nothing is so fragile as the goodwill of the citizens.[3] Lewis and Short note that the figurative uses are especially frequent.[6]

Church Latin uses it for weak, frail.[7] English has it twice: frail (mid-14th century) through Old French fraile, and fragile, first “liable to sin” (1510s) and “liable to break” about 1600.[8]
