Forms

falsare (first-person singular present fàlso, first-person singular past historic falsài, past participle falsàto, auxiliary avére)[1] Old forms include Old Italian falzare and spellings with ⟨ç⟩ such as falçato.[2][3]

Etymology

It is inherited from Late Latin falsāre (“to falsify”), a verb found in Irenaeus, formed from Latin falsus (“false”).[4][5][1][6] Zingarelli and the GDLI call the Italian word learned.[7][8] The Late Latin verb also gave Sardinian falsare in Logudorese, French fausser and Occitan falsar, and Catalan falsar, from which Spanish falsar and Portuguese falsar were taken.[9][6] In Old French the verb also meant “to prove false” and, of armour, “to break, pierce”.[9]

The Latin adjective is the past participle of fallō (“to deceive”).[10][1][2] Devoto describes the Italian verb as an intensive of the Latin verb, and Devoto–Oli and Sabatini–Coletti derive it from that verb directly.[11][12][2]

Earliest recorded meaning

The TLIO's first record is a document from Osimo dated 1151, the date Nocentini also gives.[3][4] DELI's first dated sense, “to represent something otherwise than it is”, is from Frederick II, before 1250.[5]

Semantic evolution

Old Italian used falsare for fraud of many kinds: forging a document, altering metals by alchemy, minting or clipping coins below their value, and cheating on the measure of goods.[3] Dante's forger in Hell says falsai li metalli con alchimia (“I falsified metals by alchemy”), and Giovanni Villani writes of bakers who cheated the commune falsando la misura e 'l peso del pane (“falsifying the measure and weight of bread”).[8] It also meant to betray, to break faith or a promise, to be unfaithful in love, to deceive, to show something to be false, and to damage or break something by a heavy blow, the sense Old French fausser has of armour.[3][9]

In modern Italian the main sense is to misrepresent facts, data or someone's words.[13][12] The sense “to forge” is now uncommon or literary, falsificare having taken it over.[12][2][14] Newer senses are to distort the result of a sporting competition, as unfair refereeing may do, and in tailoring to trim a garment with false pieces (falsature).[12][15][13]
