Pronunciation

  • /fɾaˈɡwaɾ/, [fɾaˈɣ̞waɾ][1]

Forms

fraguar (first-person singular present fraguo, first-person singular preterite fragüé, past participle fraguado)[1] Old Spanish wrote fraugar, also fraguar and fragar;[2][3] Aragonese texts have fraucar and frauguar.[2][3]

Etymology

It is inherited from Old Spanish fraugar, inherited from Latin fabricor (“to fashion, make”), beside the active fabricō.[2][4][5][1] The Latin verb is a derivative of fabrica (“workshop, craft”), which gave the noun fragua.[6][2] The learned fabricar is its doublet.[1]

Through a similar development French made forger, which Spanish borrowed as forjar in 1406.[2][4][7] A form with the diphthong ⟨au⟩ reduced, frogar “to build with bricks”, gave Asturian forgar (“to plane wood”).[2][8] Other cognates are Catalan fargar, Portuguese fraguar and Italian fabbricare.[8][9]

Earliest recorded meaning

Its first record in a Spanish text is in the Liber Regum (1194–1211, in a copy of the first quarter of the 13th century): Cyrus freed the Jews que fuessen fraugar el temple de Iherusalem “so that they might go and build the temple of Jerusalem”.[10][2] The Fazienda de Ultra Mar has Fraguo Moysen altar “Moses built an altar”.[10] The first sense was to build.[2]

Semantic evolution

Alfonso X's prose has both senses, to build and to forge metal.[11] Medieval Aragonese texts speak of frauguar moneda, minting coins.[2] Covarrubias in 1611 defined it as heating iron in the forge and shaping it roughly with the hammer.[12]

Autoridades added the figurative sense of devising a plan, and the masons' sense of mortar or plaster setting hard.[13] From 1869 the Academy noted that the figurative sense is mostly used in a bad sense.[14][5] In Peru it can mean to rig an election result.[15] The old sense “to build” survives among the Jews of Morocco and the East.[2]
