osprey

Etymology

It is apparently borrowed from Old French *ospreit, the Anglo-Norman form,^[2][3] recorded only in the surname Ospriet (1198),^[2][4] from Medieval Latin avis prede (“bird of prey”),^[2][5][6][4] from Latin avis (“bird”) and praeda (“booty, prey”), in the genitive praedae.^[2][6][3] Ayto gives the intermediate form as Vulgar Latin *avispreda.^[3] Other dictionaries derive it, by an unexplained route, from Latin ossifraga (“bone-breaker”), the source of ossifrage,^{[7][8][9][10][11]} formed from os (“bone”) and frangō (“to break”):^[8][3] through Old French ospres,^[7][8][9] or through an unrecorded Middle French *osfraie, the source of orfraie.^[12][13][11] The OED gives this as an alternative, with the change of f to p perhaps after prey, and compares orpres (1377);^[2] Etymonline and Ayto think the Anglo-Norman form was confused in Old French with the descendant of ossifraga.^[5][3]

Earliest recorded meaning

The large fish-eating bird of prey: about 1450, in a vocabulary printed by Wright and Wülcker,^[2] as hospray in Barnhart, with ospray before 1475.^[4][14] The 1989 edition of the OED had about 1460.^[15]

Semantic evolution

The Latin ossifraga was named by Pliny, who called it another kind of eagle; it was probably the lammergeier, which drops bones from a height to break them, and why French and English writers applied the name to the fish-eating osprey cannot now be determined.^[16][8][3] Weekley notes that neither the late appearance of the word, in the 15th century in English and French, nor its forms have been explained,^[11] and quotes Leviticus 11:13: "The eagle, and the ossifrage, and the ospray".^[11] The form aspray shows the early modern lowering of o to a.^[2] From 1885 osprey was also a milliners' name for an egret plume worn on a woman's hat or bonnet, and for artificial plumes like it.^[2][15][7]
