Pronunciation

  • Balearic, Central, Northern, Northwestern, Valencia: [ˈfals][1]

Forms

fals (feminine falsa, masculine plural falsos, feminine plural falses)[1]

Etymology

It is inherited from Latin falsus (“false, untrue”), properly the past participle of fallō (“to deceive”).[2][3][4][5][1]

The same Latin word is Occitan fals, French faux and Italian falso.[6] Meyer-Lübke took Spanish falso and Portuguese falso from the Occitan and Catalan form,[6] while Corominas explains the kept /l/ of the Spanish word by the speech of the educated, above all the clergy, who used it in moral judgements.[7]

De Vaan derives the Latin verb from *sgʷʰh₂(e)l-n- (“to stumble”), the root of Ancient Greek σφάλλω (sphállō, “to bring down”).[8]

Earliest recorded meaning

The Homilies d'Organyà have the word in a list of sins, per ladronici o per tolta o per fals jutgament “through theft or seizure or false judgement”, and speak of los falses judeus “the false Jews”.[2] The sense is “untrue, deceitful”.[2]

Semantic evolution

Llull writes of a falsa temptació of the devil and of Muhammad as lur fals proffeta “their false prophet”;[2] Jaume I already applies the word to counterfeit coins, morabatins falses de coyre.[2] In Jaume I's chronicle a people is molt falsa, untrustworthy.[9] Eiximenis uses it for “weak”: hom fals és mur fals, a false man is a wall that falls at the first attack.[9] As a noun it meant a falsehood, and the Valencian Furs speak of the crim de fals, the crime of forgery.[9]

Some uses are material: the porta falsa is a small back door, a figure for the anus in Pou's dictionary;[2] la falsa is the attic in Puigcerdà, Mequinensa and the Maestrat, as in Upper Aragon and Murcia; and Mallorca has place names such as Es Corral Fals.[2] The derivatives are old: falsari “forger” from 1272 in the Costums de Tortosa, falsament and falsia in the 14th century, falsedat in 1490 in the Tirant.[4][2]

Labèrnia's dictionary of 1839 records the phrase en fals “without proper security, falsely”, and Tarongí's of 1878 the comparison més fals que Judes.[10][11] Modern dictionaries add senses in diplomatics and numismatics: a forged document, a counterfeit coin.[5]
