Pronunciation
- /ˈoso/, [ˈo.so][1]
Forms
oso m (plural osos, feminine osa, feminine plural osas)[1] Old Spanish wrote osso beside oso, with the voiceless /s/ the word always had in the old language; the Libro de Alexandre has orso, orsa.[2][3] Aragonese and Navarrese onso is recorded from about 1200, and Judeo-Spanish has lonso.[2][4]
Etymology
It is inherited from Old Spanish osso, inherited from Latin ursus (“bear”).[2][5][6][1] Wiktionary sets up an intermediate Vulgar Latin form *ussus, with the Latin cluster /rs/ assimilated to /ss/;[1] Corominas notes that Castilian and Catalan make this assimilation regularly.[1][2] The feminine osa continues ursa.[6][5]
The word is common to all the Romance languages: Asturian osu, Galician oso, Catalan ós, French ours, Italian orso and Romanian urs.[1][7][4] Corominas calls Portuguese urso semi-learned.[2] Old Portuguese had usso and osso;[8][9] Nascentes thinks the second form was given up because it sounded like the word for “bone”.[8][9] Aragonese onso and Old Catalan ons got their /n/ from the very frequent phrase ⟨un oso⟩, which spread its nasal to the noun, as in Extremaduran ⟨el nosu⟩;[1][10] Judeo-Spanish lonso is a dissimilated form of ⟨un nonso⟩.[2]
The Latin noun goes back to Proto-Indo-European *h₂ŕ̥tḱos (“bear”), the source also of Ancient Greek ἄρκτος (árktos).[1][10] De Vaan points out that the Latin initial u- is irregular, since *orsus would be expected, and suspects a taboo distortion of the name of the animal.[10] The DHLF adds that Germanic, Baltic and Slavic replaced the inherited word with new names, also because of a hunting taboo.[11]
Earliest recorded meaning
The DCECH's first record is a charter of 1032, and the word is in Berceo.[2][5] Alfonso X's Lapidario (1250–1279) says of a stone that where it lies no fazen danno … leones ni ossos “neither lions nor bears do harm”, the animal sense that the word has had in every period.[12][2]
Semantic evolution
Covarrubias in 1611 takes the name from Latin ursus, reports a fanciful Hebrew etymology, and repeats the story that a bear killed King Favila while he was hunting.[13] The Diccionario de Autoridades describes the bear of the Spanish mountains, which climbs trees and steals beehives for their honey; the Academy later named this one oso colmenero.[14][15] The Academy added oso blanco in 1817 and oso marino, a seal, in 1843.[15][16] In the Americas the name was given to other animals: an account from Santo Domingo of 1549 already describes the oso hormiguero, the anteater.[17]
Applied to people, the noun names a very hairy or ugly man, and in slang a large hairy gay man.[18][1] In Mexico oso is an embarrassing or ridiculous act, as in hacer el oso; in Colombia it is the shyness felt when saying or doing something; in Cuba and the Dominican Republic it is a bully or braggart.[19][20][21][22]
