  • Balearic, Central: [fiˈnes.tɾə][1]
  • Northwestern, Valencia: [fiˈnes.tɾa][1]

Forms

finestra f (plural finestres)[1] Medieval documents often write fenestra, the form expected from the sound changes, in the Vides de sants rosselloneses, in Llull and in Vicent Ferrer's sermons, and in a Barcelona document as late as 1431.[2] Today the form with fi- is general in every dialect.[2] The DCVB records the pronunciations [fiˈnɛstɾə], [fiˈnɛstɾa], [fiˈnɛstɾo], [fiˈnestɾə] and [fiˈnestɾɛ].[3]

Etymology

It is inherited from Latin fenestra (“window”).[2][3][4][5][1]

The same Latin word is Italian finestra, French fenêtre, Occitan fenèstra, Romanian fereastră, Old Spanish finiestra and Portuguese fresta.[6]

The ⟨i⟩ of the first syllable is irregular in Catalan, where the medieval ⟨fenestra⟩ is the regular outcome; in Italian, pretonic ⟨e⟩ becomes ⟨i⟩ regularly, and the Old Spanish and Galician forms have their own explanations.[2] Coromines does not think the change phonetic.[2] He traces it to place names: Finestres, recorded from 947, Finestrelles, from 1011, and others are high lookout points, compared to the window of a watchtower, and since they usually stand on district or parish boundaries, Latin fines (“boundaries”) acted on them as a folk etymology, changing ⟨fen-⟩ to ⟨fin-⟩; from the place names the variant spread to the common noun.[2] Part of Occitania has a parallel form with ⟨fi-⟩, but there the regular form prevails.[2]

The origin of the Latin word is unknown to the OLD;[7][1] Wiktionary takes it to be apparently Etruscan.[7][1]

Earliest recorded meaning

Bruguera and the GDLC date the word to the 13th century, in the Vides de sants rosselloneses;[5][4][2] Coromines dates the common noun to the end of that century, and it appears in Latin documents of Catalonia as a place name from the 10th.[5][4][2] In the Vides a holy man throws a bag of gold into a house per una fenestra, at night.[2] Llull writes of a palace hon havia moltes finestres through which the sunlight came in.[2][8]

Semantic evolution

The Costums de Tortosa regulate the windows that may be opened in party walls and over streets.[2] Llull uses the window as an image: as windows are in a room so that the sun may show its brightness there.[8] In the Curial e Güelfa (1440) fer finestra means to open a gap to see through, and in Roig's Spill (1460) a good wife tendrà baldes a la finestra, will keep the house shut and spend little.[9]

Derivatives appear from the 14th century: finestrejar in Eiximenis, finestró in 1546, finestral in the 17th century, finestrer in Verdaguer c. 1900.[5] Learned words such as defenestració were formed from the Latin.[5] Fabra's dictionary of 1932 records tirar la casa per la finestra, to spend lavishly.[10] The modern dictionaries add the window of a car or train, openings in anatomy and an interval in physics.[4]
