Forms

fuerza f (plural fuerzas)[1] Old Spanish wrote forza and fuerça; the Leonese form forcia is in the Libro de Alexandre, and Asturian has fuercia.[2] Old Castilian also had huerza, and popular speech in Navarre says juerza.[3]

Etymology

It is inherited from Late Latin fortia (“strength”).[2][4][5][1] Old Spanish wrote fuerça.[2][1] The Late Latin noun, found from the 2nd century in Commodian and Firmicus Maternus, replaced classical vīs in all the western Romance languages.[2] It was the neuter plural of Latin fortis (“strong, brave”), taken from phrases such as fortia facta (“brave deeds”).[1]

The same word is Portuguese força, Galician forza, Catalan força, French force and Italian forza.[6][3][7] The Latin adjective, Old Latin forctis, is from Proto-Italic *forkti-; de Vaan considers two Proto-Indo-European sources, a root meaning “high” and Proto-Indo-European *dʰerǵʰ- (“to make firm”), without deciding between them.[8][1]

Earliest recorded meaning

The first record is forza in a charter of 1115.[2][4] The Cantar de mio Cid (c. 1140, in a 14th-century copy) has fuerça, in the plural fuerças.[2][9] The Fuero de Madrid punishes the man qui intrare cum forza “who enters by force”.[9]

Semantic evolution

Alfonso X's prose has the main senses of today: physical strength, the natural power of a thing (the stone that draws iron con muy grand fuerça), armed forces, and violence.[10] Covarrubias in 1611 adds courage, the force of an argument, violence done against someone's will, with the proverb Do fuerça ay derecho se pierde “where there is force, right is lost”, and a fortified castle.[11] The sense “fortress” is also the first in the Americas, in Tierra Firme in 1513.[12] The Academy's 1884 edition still defines it as a strength able to lift a stone or a bar, as the Autoridades had done in 1726–1739.[13][14] In physics it names a cause that changes the motion of a body.[1]
