Forms

inferno m (plural infernos)[1] Old Galician-Portuguese also wrote iferno, infferno and ynferno.[2][3][1]

Etymology

It is inherited from Latin īnfernus (“hell; the underworld”), written Old Galician-Portuguese inferno or Old Galician-Portuguese iferno in the oldest texts.[4][5][1] In classical Latin the word was an adjective meaning “lying lower, of the regions below”, and its neuter plural was used for the underworld; the singular noun “hell” belongs to the Christian writers.[4][6][7] Wiktionary explains the noun as short for a phrase with locus (“place”), “the nether place”.[1] The adjective was formed from the stem of īnferus (“below, beneath”), the source of Portuguese ínfero, perhaps after supernus (“upper”).[6][1] Nascentes considers the word learned, the old form without n having been reshaped after the Latin.[8]

The same Latin word is Galician inferno, Spanish infierno, Catalan infern, French enfer and Italian inferno; it was also borrowed into Welsh.[9][10]

Earliest recorded meaning

A document of 1228 has e cum Judas traedor no inferno danado “and with Judas the traitor damned in hell”, and one of 1271 seya danado por ja mays no infferno “may he be damned for ever in hell”.[2] The Cantigas de Santa Maria speak of breaking open the old hell (britaria o inferno antigo).[2] Houaiss and Cunha date the word to the 13th century.[4][5]

Semantic evolution

The Miragres de Santiago already use the plural os infernos for the place to which Christ descended.[2] Morais in 1789 adds two technical senses, the hole in which the wheel of a water mill turns and a vat of the mill into which the mash is drawn off, and the popular phrase fazer inferno a alguém “to make a row, to try someone's patience”.[11] The mill and olive-press senses are still recorded in Portuguese dialect surveys.[12] Figurative senses, “a torment”, “great disorder”, “a very hot place”, are given by the modern dictionaries, as is the locked section of a library where licentious books are kept.[4][13][1] Inferno Verde, “the green hell”, is a literary name for Amazonia.[13][14]
