Pronunciation
Forms
acidente m (plural acidentes)[1] Houaiss records acidente, acçidente and açidemte in the 15th century.[2] The etymological spelling accidente was the main one until the 20th century: Bluteau and Feijó head the word so, and Vieira (1871) and Figueiredo (1899) refer acidente to accidente.[3][4][5][6]
Etymology
It is borrowed from Latin accidēns (“chance event; non-essential quality”), a learned word.[2][7][8][1] The Latin noun is the present participle of accidō (“to fall upon; to happen”), which is formed of ad- (“to”) and cadō (“to fall”).[2][9][1] Nascentes calls it semi-learned.[10]
The same Latin word was taken into Spanish accidente, recorded about 1300, French accident, from 1170, Italian accidente, Catalan accident and Romanian accident.[11][12][1] De Vaan reconstructs the Latin verb for “to fall” as Proto-Indo-European *(ḱe-)ḱh₂d- (“to fall”), with a question mark,[13] and Wiktionary gives *ḱad- (“to fall”).[1]
Earliest recorded meaning
Houaiss dates the noun to the 14th century, Cunha and Machado to the 15th.[2][7][8] Machado's 15th-century quotation sets acidentes beside gold and silver as the worldly things a good man must despise: ouro e prata e outros muytos acidentes cordiaaes deste mundo “gold and silver and many other accidents of this world that please the heart”.[8]
Semantic evolution
Barbosa's dictionary of 1611 gives the Latin accidens and, for acidente de doença, the Greek-derived symptoma.[14] Bluteau (1712) explains the two learned senses: in philosophy, what is not of the substance of a thing, like the whiteness of a wall, and in medicine, a dangerous turn that comes on a patient in the course of an illness.[3] Grammar used it for the inflections of a word, gender, number and person.[15] The everyday sense of an unhappy event that causes harm has become the main one, with phrases such as acidente de trabalho “accident at work” and, in Portugal, acidente de viação “road accident”.[2][16] In popular use it also means a fainting fit or an epileptic seizure.[2][17]
