Etymology and origin of the Catalan word os

Catalan has two nouns spelled os: the bone, from Latin ossum, and the bear, from Latin ursus, which Fabra and the DIEC2 write ós.[1][2][3][4]

Pronunciation

  • Northern: [ˈo̞s][2]
  • Balearic, Central, Northwestern, Valencia: [ˈɔs][2]

Forms

os m (plural ossos)[2] Medieval texts have the plurals osses (Llull, Muntaner) and ossos (the Spill).[5][6] Old Catalan also used ossa, from the Latin neuter plural, for a set of bones or a person's remains.[7][5]

Etymology

The word for the bone is inherited from Old Catalan os, which is inherited from Latin ossum (“bone”), a form recorded from Accius on beside classical os (genitive ⟨ossis⟩).[5][8][7][9][2]

The same Latin word is Spanish hueso, French os, Italian osso, Portuguese osso and Romanian os.[10] The collective ossa continues the Latin neuter plural.[7]

De Vaan reconstructs Proto-Italic ⟨ost⟩, genitive ⟨ostos⟩, and *h₃o/est- (“bone”), the source also of ὀστέον (ostéon) and of the Hittite and Sanskrit words for bone.[9][2]

Earliest recorded meaning

CICA's earliest record of the word is in the Usatges de Barcelona, in the first half of the 13th century.[11] Llull writes in the Llibre de contemplació that the bone is formed within the flesh, and speaks of the marrow nourished in the bones.[6][12] From the start it meant the hard pieces of the skeleton.[12]

Semantic evolution

Medieval texts also use os for the stone of a fruit, as the medical Tròtula does for dates and olives, and for worked bone used in place of ivory: an inventory of Alfonso the Magnanimous of 1413 lists chessmen of bone.[12] The Spill has haver gran os a roure “to have a big bone to gnaw”, a great difficulty.[5]

Ossos for a person's mortal remains appears in the early 17th century, where older texts mostly said ossa; the oath pels ossos de mon pare is already in the Tirant.[5] Other phrases followed: os de sípia “cuttlebone” in 1523, os de peix “fishbone” in 1524, os bertran “sacrum” in Labèrnia (1839).[5] The DCVB and the GDLC record figurative senses: a difficult thing or person, and laziness.[8][1]

Among the derivatives, ossera is recorded in 1415, ossam in the 15th century, desossar in 1472, osset and ossut in 1696 and ossada about 1900, in Verdaguer.[7][5]

Pronunciation

  • Northern: [ˈus][2]
  • Balearic, Central, Northwestern, Valencia: [ˈos][2]

Forms

os m (plural ossos, feminine ossa, feminine plural osses)[2] Fabra and the DIEC2 write the bear ós, plural óssos.[3][4] Wiktionary gives ós as an alternative spelling.[2] Old Catalan had ós (in Llull's Llibre de meravelles), ors, which Llull seems to have preferred as more literary, and onso, feminine onsa, frequent in Valencian texts.[15] Today ós is said in Barcelona and most of Catalonia, in the Pallars and in much of Valencia;[15] onso in Mallorca, Menorca, Tortosa and the south of the province of Lleida;[15] orso in parts of Valencia (the Horta, the Ribera del Xúquer, Alcoi, Carlet); and urs in Roussillon.[15] In some places the feminine óssa is the generic name, used even of the male.[15]

Etymology

The word for the bear is inherited from Latin ursus (“bear”).[15][16][7][1][2]

The same Latin word is French ours, Occitan ors, Spanish oso, Italian orso and Romanian urs.[17][2] Coromines takes the medieval ors for a half-learned or Occitanising form, and the Roussillon ⟨urs⟩ for an Occitanism.[15]

The Old Catalan variant onso has an unexpected /n/, like Aragonese onso.[15][18] Coromines explains the Aragonese form by the spread of the nasal of the indefinite article in ⟨un oso⟩, the bear being a solitary animal spoken of mostly as “a bear”, and takes the Catalan one for a Mozarabic or Aragonese loan, given its early Valencian records.[15][18]

Latin ⟨ursus⟩ goes back to *orsos and *h₂ŕ̥tḱos (“bear”), the source also of ἄρκτος (árktos) and art.[9][2] According to de Vaan the Latin cluster -rs- continues the PIE *-rtḱ-, and the initial vowel, where ⟨ar-⟩ would be expected, points to some kind of taboo distortion of the name.[9]

Earliest recorded meaning

CICA's earliest record is ors in the Catalan Diàlegs of St Gregory, of the second half of the 13th century (in a copy of 1340).[19] In Llull's Llibre de meravelles (1288–1289) the bear, with the leopard, admits that even they, who are stronger, are afraid of a voice they hear.[20][15] The word meant the animal.[15]

Semantic evolution

Llull uses ors many times in the Llibre de meravelles and the Blaquerna; it is also in the Costums de Tortosa, the Tresor de pobres and Vicent Ferrer's sermons, beside onso.[15] A document of 1444 from Barcelona has both forms together, lo ós o onso.[15] The feminine óssa is recorded from the 14th century, and the constellations Óssa Major and Óssa Menor from Lacavalleria (1696), who writes onsa.[15]

The dictionaries after 1500 give ós or onso;[15] Labèrnia (1839) takes ós as the normal form and records ós blanc, the polar bear.[15] Fabra's dictionary of 1932 adds ós formiguer, the anteater, and the phrase viure com un ós, to live apart from other people.[3]

Timeline

  • 1250–1299 – ors in the Catalan Diàlegs of St Gregory (copy of 1340), the earliest record in CICA.[19]
  • 1288–1289 – Llull's Llibre de meravelles has lo Ós among the animals of its fables.[20][15]
  • 1328 – honsos in the Privileges of Catí, in the Maestrat.[15]
  • 1370 – Peter the Ceremonious, at the Corts of Tarragona, recalls David defending his father's flock from the lion and the ors.[21]
  • 1444 – a Barcelona document writes lo ós o onso.[15]
  • 1696 – Lacavalleria records the constellations, as onsa.[15]
  • 1839 – Labèrnia treats ós as the normal form.[15]
  • 1932 – Fabra's Diccionari general records ós formiguer.[3]

Meanings

Noun

  1. bear: a large, heavily built carnivorous plantigrade mammal of the family Ursidae, with thick fur and a very short tail: Als Pirineus encara hi viuen alguns ossos.[4][1]
  2. os bru, the brown bear (Ursus arctos); os blanc or os polar, the polar bear (Ursus maritimus).[4]
  3. os formiguer, the giant anteater, a xenarthran of America.[4][3]

Usage notes

The DCVB also heads os as a dialect form of the pronoun us, and as a written contraction of o es.[8]
