Forms
adeus[1] Bluteau (1712) heads the word adeos and refers adeus to it;[2][3][4] Morais (1789) refers adeos to deos.[2][3][4]
Etymology
It is formed from Portuguese a + deus, “to God”, the last words of farewell phrases meaning “I hand you over to God” or “I commend you to God”.[5][6][7][8] Wiktionary instead calls it a learned borrowing from Medieval Latin ad Deum (“to God”).[1]
The other Romance languages have the same farewell: Galician adeus, Spanish adiós, Catalan adeu, French adieu and Italian addio.[1][9]
Earliest recorded meaning
Houaiss dates both the noun and the interjection to about 1538.[5] Cunha dates the word to the 16th century, and in the Post Scriptum letters it first appears in 1570.[6][10] Machado illustrates the full phrase from which it was shortened with Sá de Miranda's Deixote a Deus “I leave you to God”.[11]
Semantic evolution
Bluteau describes adeos as the word Christian courtesy uses on parting, and renders it by Latin vale.[3] Vieira lists proverbial uses, among them adeus, cestos, estão feitas as vindimas “goodbye, baskets, the grape harvest is done”, said of things no longer needed.[12]
As an interjection it says goodbye, usually before a long parting, but it is also a greeting between people who meet or pass each other; it also mourns something lost (adeus, juventude) and expresses disappointment.[5][8] As a noun it is a farewell and, by extension, a parting;[1] dizer adeus a is to give something up, and adeus de mão fechada is a Brazilian informal name for a threatening gesture.[5] Papiamentu has ayó from it.[1]
