Forms
ano m (plural anos)[1] Houaiss records the medieval spellings ano (1273), año (1275) and ãno (1278).[2] Wiktionary and García de Diego give the older spelling anno.[1][3]
Etymology
It is inherited from Latin annus (“year”), written Old Galician-Portuguese ano in the oldest texts.[2][4][5][1]
The same Latin word is Galician ano, Spanish año, Catalan any, French an, Italian anno and Romanian an.[6][1]
The Latin word goes back to *atnos, from *h₂et-no-, probably a derivative of *h₂et- (“to go”), so that the year was first “that which goes”.[7][1] Its closest relatives are in Italic and Germanic: Gothic has 𐌰𐍄𐌰𐌸𐌽𐌹 (ataþni, “year”).[8][1] Lewis & Short still report the older view that it came from anus (“ring”), the year as a circuit of time.[9]
Earliest recorded meaning
Lorenzo's chronology quotes a Latin charter of 1047 with the Romance-looking plural anus (per singulos anus, “for each year”).[10] The first record in Portuguese is in the Testament of Afonso II of 1214, which orders three commemorations a year (en tres partes do ano).[10] Machado's first quotation is a document of 1264 dated na Era de Mil e CCC e dous anos.[4] In these texts the word already has its modern sense, a period of twelve months.[10]
Semantic evolution
The Cantigas de Santa Maria use it in phrases still current, such as cad'ano “every year” and a cabo dun ano “after a year”, and the profane cantigas already have Ano Novo for the first of January.[11]
Later dictionaries add the astronomical definition, the time the Earth takes to go round the Sun, and extend it to other planets (o ano de Júpiter).[2][12] The plural anos came to mean a person's age and, in Portugal, a birthday: fazer anos is “to have a birthday”, and the dia de anos is the birthday itself.[13][14] Phrases such as ano escolar, ano agrário and ano fiscal name a yearly cycle that does not begin in January.[2][13]
The word passed into the Portuguese-based creoles: Kabuverdianu ánu, Guinea-Bissau Creole anu and Papiamentu aña.[1]

Usage notes
Ano Novo (also ano-novo) is New Year's Day or the year that begins, and ano-bom is an older name for the first of January.[13][14]
Houaiss and Aurélio also record a separate, rarely used masculine noun ano “anus”, which Houaiss dates to Morais's dictionary of 1789.[2][12] Morais defines it as a medical term, and Vieira derives it from Latin anus (“ring”), noting that the Latin form ânus is the usual one.[17][18]
