Forms

purgar (first-person singular present purgo, first-person singular preterite purguei, past participle purgado)[1]

Etymology

It is borrowed from Latin purgō (“to clean, purify; to excuse”), first recorded in the 13th century as the participle Old Galician-Portuguese purgada.[2][3][4][1] Houaiss analyses the Latin verb as a compound of pūrus (“pure”) and agō (“to do, make”).[2] The OLD explains it as the adjective with the verb-forming suffix -igō, from the older pūrigō of Plautus and Varro.[5] Wiktionary reports that de Vaan takes the first part from Proto-Italic *pūr (“fire”) instead, so that the verb first meant “to carry the fire around”.[1] The adjective goes back to Proto-Indo-European *ph₂u-ro- (“clear, cleansed”).[6]

The same Latin verb is Spanish purgar, Italian purgare and French purger.[7] Corominas treats the Spanish verb as taken from Latin, first recorded in 1220–1250.[8] Forms with /o/ such as Catalan porgar “to sift” and Old Spanish porgar also exist, and the REW notes that the verb may have had a short /u/, in which case these would be the older forms and those with ⟨u⟩ were reshaped after the Latin adjective.[7][9]

Earliest recorded meaning

Cantiga 75 of the Cantigas de Santa Maria has quero que ant'un pouco sejas ja quanto purgada “I want you to be somewhat cleansed before long”.[3] Houaiss dates the infinitive form purgaren to the 14th century.[2]

Semantic evolution

Notarial records of Noia in Galicia use the verb in a legal sense in 1407: a man must come a purgar súas contomasjas et rrebeldías, to make good his failures to appear in court.[3] Morais (1813) lists cleansing the body of bad humours with purges, purifying metals of their dross, purging errors, expiating a fault, the intransitive “to discharge a bad humour” and the reflexive purgar-se “to take a purge”.[10] Vieira (1871–1874) adds purifying sugar and the legal phrases purgar a mora, of a tenant who shows a valid reason for paying his rent late, and purgar a revelia.[11] In the north of Portugal the vine is said to purgar when it drops its flowers.[12][13]
