Pronunciation

  • Balearic, Central: /sun/[1]
  • Valencia: /son/[1]

Forms

son m (feminine sa, masculine plural sos, feminine plural ses)[1]

Etymology

The possessive is inherited from Old Catalan son, which is inherited from Vulgar Latin sum, the reduced form of Latin suus (“his, her, its own”) in its accusative ⟨suum⟩.[1][2][3] Before a noun Vulgar Latin ⟨suum⟩ and ⟨sua⟩ were monosyllabic and became ⟨son⟩ and ⟨sa⟩.[1][3] Stressed, they gave seu.[1][3] Bruguera lists ⟨son⟩ and ⟨sa⟩ under ⟨seu⟩.[4]

The same unstressed form is Occitan son and French son.[1][5]

Latin ⟨suus⟩ is from Proto-Italic *sowos and Proto-Indo-European *sewos, from *swé (“self”).[1]

Earliest recorded meaning

The weak forms appear from the beginnings of the written language: the Homilies d'Organyà speak of a man who tanca sa casa o son castel “locks his house or his castle”.[3] The GDLC also dates the word to the 12th century, with the Homilies.[2] CICA dates the Homilies between 1175 and 1224.[6]

Semantic evolution

Medieval prose uses son, sa, sos, ses freely before nouns, as Eiximenis does: ço del seu a son prohisme “of what is his to his neighbour”.[7] Jaume I's chronicle and other archaic texts also use them for a plural possessor, “their”, where the medieval norm was llur.[3]

The weak forms later receded everywhere, and in the modern spoken language they survive mainly with kinship terms (son pare, sa mare).[3] Verdaguer still preferred them in verse.[3] Coromines heard the fixed phrase ha costat sos duros “it cost a fair sum” from old people in Barcelona around 1914; a romance collected at Girona has the analogical feminine suna for sa.[3]

Timeline

  • 1175–1224 – son castel in the Homilies d'Organyà.[3][6]
  • 1244–1274 – Jaume I's chronicle uses son and ses also for “their”.[3]
  • 1381 – Eiximenis: a son prohisme.[7]
  • c. 1914 – Coromines hears ha costat sos duros in Barcelona.[3]

Meanings

Determiner

  1. his, her, its; the unstressed possessive, used before the noun, today mostly with kinship terms: son germà, sa cosina.[2][1][3]
  2. (archaic) their.[1][3]
  3. your, referring to the person addressed as vostè.[1]

Pronunciation

  • Northern: [ˈso̞n][1]
  • Balearic, Central, Northwestern, Valencia: [ˈsɔn][1]

Forms

son m (plural sons)[1] The DCVB records the pronunciations [sɔ́n], [sɔ̞́n], [sɔ́] and [sɔ̞́].[8] The word is masculine in the sense “sleep” and feminine in the sense “sleepiness”.[9][10]

Etymology

The word for sleep is inherited from Old Catalan son, which is inherited from Latin somnus (“sleep”).[11][8][12][2][1]

The same Latin word is Spanish sueño, which in Spanish merged with the descendant of somnium (“dream”), and Occitan sòm.[13][14]

The Latin noun is from Proto-Italic *swepnos and Proto-Indo-European *swépnos, and is cognate with Ancient Greek ὕπνος (húpnos) and Sanskrit स्वप्न (svapna).[1][15]

Latin ⟨somnus⟩ was masculine, and the masculine suits a Catalan word ending in a consonant; but the feminine words close to it in sense, fam “hunger” and set “thirst”, made ⟨son⟩ feminine as well, above all in the sense “wish to sleep”.[11][8][1]

Earliest recorded meaning

Coromines finds the word from the beginnings of the language; his first quotation is a document of 1250 from the Alt Cardener, vengren ... prim son passad “they came when the first sleep was over”.[11] Bruguera and the GDLC date it to 1250.[12][2] Jaume I's chronicle tells how the ship of Guillem de Montcada caught up with the king's prop del primer son, near the first part of the night.[11]

Semantic evolution

In the medieval texts the word means both the state of sleep and the act of sleeping at a given time, especially its first part, the prim son.[11][7] At first the two genders alternate in every sense: a document of 1295 has el primer son and one of 1387 a hora de prima son.[11] The feminine soon prevailed in the sense “desire to sleep”: Bernat Metge writes sobtat de molta son “overcome by great sleepiness”.[11]

Labèrnia in 1839 already separates the feminine, the inclination to sleep, from the masculine, the act of sleeping.[16] Fabra fixed the distinction in 1932, with phrases such as tenir el son lleuger “to be a light sleeper” and caure de son “to be dropping with sleep”.[10] The compound entreson is a light, interrupted sleep.[12]

Timeline

  • 1250 – prim son in a document from the Alt Cardener.[11][12]
  • 1272 – Llull's Blanquerna: prim son.[7]
  • 1295 – el primer son, masculine, in a document of Camarasa.[11]
  • 1387 – a hora de prima son, feminine.[11]
  • 1396 – havien dormit ja un son in a criminal trial.[7]
  • 1839 – Labèrnia separates the feminine “sleepiness” from the masculine “sleep”.[16]
  • 1932 – Fabra heads the word as masculine and feminine.[10]

Meanings

Noun

  1. (masculine) sleep, the state of rest in which consciousness is suspended: Té el son molt lleuger.[9][2][1]
  2. (masculine) A spell of sleep, as in fer un son “to have a nap”.[9][7]
  3. (masculine) el primer son, el prim son: the first hours of the night's sleep.[7][10]
  4. (feminine) sleepiness, the wish to sleep: tenir son, caure de son.[2][8][10][1]

Usage notes

Other words spelt son: the DCVB refers a son “sound” to so, a spelling Llull uses.[8][17] In Balearic place names Son (feminine So Na) precedes a personal name to name a country estate, Son Cervera; it is a contraction of ço d’En, “that of Mr …”.[8][2][12] The DCVB rejects Griera's derivation from Latin solum “ground”.[8] The DCVB also records son as an old form of the first person of ésser, “I am”, and the GDLC a son, a unit of loudness in acoustics.[8][2]
