Pronunciation

Forms

ongle m (plural ongles)[1] Old French ungle, usually feminine until the 16th century.[2][3] Anglo-Norman ongle, oungle, ungele.[4]

Etymology

It is inherited from Old French ungle, inherited from Vulgar Latin *ungla, a syncopated form of ungula (“claw, talon, hoof”), from unguis (“nail”).[3][5][1] The base word disappeared early, as it left no trace in the Romance languages;[3][6] Bloch and Wartburg and the TLFi see the use of the derivative as popular in origin, like other Vulgar Latin names for parts of the body (compare jambe).[3][6] Until the 16th century the word was mostly feminine, like its Latin source, and La Fontaine still made it feminine.[3][2][6]

Cognate with Italian unghia, Romanian unghie, Occitan ongla, Catalan ungla, Spanish uña and Portuguese unha.[7][8] The Latin word for nail goes back to Proto-Indo-European *h₃negʰ-, whose descendants include Ancient Greek ὄνυξ (ónux) (borrowed as onyx), Old High German nagal and Lithuanian nagas.[1][9][8]

Earliest recorded meaning

Its first record, in the Voyage de saint Brendan (early 12th century), is for the talon of a bird of prey.[3][9] The wolf's claw follows in Philippe de Thaon's Bestiaire (1121–1134), and the human nail about 1130, in the Laws of William: al ungle del petit dei “at the nail of the little finger”.[3][8]

Semantic evolution

The word was first used of animals, naming the talons of birds of prey, the claws of carnivores and the hooves of ungulates; phrases now said of people, such as avoir bec et ongles (1606), come from this use.[9][3] From about 1130 it also named the human nail, and entered the phrases ronger ses ongles (1370), figuratively “to fret” from Montaigne (1580), and rogner les ongles à quelqu'un “to curb someone's power” (14th century).[3][9]

Sur l'ongle “perfectly” (1606) translates Latin ad unguem, which Erasmus took for a metaphor from marble workers testing a surface with the nail; it lives on as jusqu'au bout des ongles (1694).[9][3] Avoir les ongles crochus, first a description of a usurer (1842), came to mean “to be grasping” (1896).[3][9] By analogy the word was used in veterinary medicine (early 14th century) and for hook-shaped instruments of torture (1366).[3][9]
