Forms

subsídio m (plural subsídios)[1] The oldest record and Cunha have the spelling sossidio.[2][3] Wiktionary also lists subsidio as an alternative form.[1]

Etymology

It is borrowed from Latin subsidium (“reserve troops; help, support”), a learned word.[4][3][1][5] Houaiss dates it to the 15th century, and Lorenzo's chronology antedates Machado's 16th-century record, taken from Morais, to 1428, with the spelling Old Galician-Portuguese sossidio.[4][2]

The same Latin noun is Galician subsidio, Spanish subsidio, Catalan subsidi, French subside, Italian sussidio and Romanian subsidiu.[1][6] The Spanish word is first recorded in 1438, the French one in 1236.[7][8]

In Latin the noun is formed from sub- (“under”) and sedeō (“to sit”) with the suffix -ium.[9][1] It was first a military term, the troops held back in the third line of battle as a reserve;[9][10] Varro explains the name from their waiting there.[9][10] From this came "help, support" and "refuge".[8]

Earliest recorded meaning

The record of 1428 in Lorenzo's chronology speaks of the men who apportioned a sossidio and of the collector of that sossidio, that is, a tax or levy.[2] Medieval Latin already used the noun for the aid a vassal owed his lord.[11]

Semantic evolution

Morais (1789) defines subsídio as help in money, soldiers or supplies for a military action or any civil or political enterprise, and records the subsídio litterario, the tax paid to support teachers.[12] Bluteau (1712) gives both the military sense, "military help, reinforcement", and the general "aid".[13] The modern senses are money: a grant from the state to an industry, to public works or to an allied state, and in Brazil the pay of members of the legislature.[4][14] In the plural the word also means data or material for a study.[4][15] In Portugal subsídio is also a benefit paid to a worker, as in subsídio de desemprego and subsídio de férias.[16][15]
