Pronunciation
Forms
idade f (plural idades)[1] Old Galician-Portuguese wrote ydade and jdade, and idade from the 14th century.[2][3] The spelling edade, of the 18th century, imitated the Latin.[2] Silva Bastos (1912) still enters idade as a spelling that some lexicographers followed for edade.[4][1]
Etymology
The word is inherited from Latin, written Old Galician-Portuguese ydade and Old Galician-Portuguese jdade in the oldest texts, but the sources disagree on the Latin form.[2][3]
Houaiss takes it as inherited from Latin aevitās (“lifetime, age”), the archaic form that Latin replaced with aetās: the Portuguese word has initial /i-/ from its first records, whereas the classical form would require an old form with /e-/, which is not found.[2] Nascentes first followed the classical form, but in 1966 chose the archaic one, through an older form with /ei-/ that Galician eidade and a Leonese form still show; the REW lists the Portuguese word in the same group.[2][5][6][7] Cunha, Aurélio, the DLP and Wiktionary derive it from the classical form.[3][8][9][1]
The classical word is a contraction of the archaic one, which is aevum (“duration, lifetime”) with the suffix -tās.[10][1] It goes back to Proto-Italic *aiwotāts and Proto-Indo-European *h₂eyu- (“vital energy; lifetime”).[11][12] The same Latin word is Spanish edad, Catalan edat, Occitan edat and Italian età, while French âge comes from a derivative.[7][6]
Earliest recorded meaning
Houaiss and Cunha date ydade and jdade to the 13th century.[2][3] The Portuguese translation of the Fuero Real has todo ome que nõ for de ydade “every man who is not of age” and de ydade conprida “of full age”, and a charter of 1288 speaks of a person reaching the age to manage his property.[13]
Semantic evolution
The medieval chronicles already use the word for a person's years, tan pequeno era de jdade que non auja aynda vijnt años “he was so young that he was not yet twenty”, and for old age, de grande ydade.[13] Bluteau distinguishes four senses: the whole course of a life, each stage of it, the time already lived, and time in general, an era.[14]
From the sense “era” come the names of historical and prehistoric periods, Idade Média and idade da pedra, and geology uses the word for its smallest unit of time.[2][8][15] Modern phrases are terceira idade “old age” and idade crítica “menopause”.[16][2]
