Etymology tree
From the same root
Forms
moio m (plural moios)[1] The medieval texts write moyo, plural moyos, and Houaiss also records mojos in 1392.[2][3] The spelling moyo heads the word in Cardoso (1569) and Pereira (1697), while Morais (1789) refers moyo to moio.[4][5][6]
Etymology
It is inherited from Latin modius (“a dry measure, peck”), written Old Galician-Portuguese moyo in the oldest texts.[3][7][8][1] The DDGM's glossary of the Crónica Geral gives the same etymon and follows the word back to Latin charters of the 11th century.[2]
The same Latin word is Galician moio, Spanish moyo, Italian moggio and French muid.[9][1][10] García de Diego records moyo as an old Castilian word and treats modio as a learned form.[11]
In Latin the noun was formed modus (“measure”) with the suffix -ius.[1][12] De Vaan traces the Latin noun to Proto-Italic *medo- and to a Proto-Indo-European noun *med-o- (“measure”), from the root *med-.[13]
Earliest recorded meaning
Latin charters already use the Romance form: one of 1080 has per suos moios “by their moios” and one of 1115 a price of ten moios.[2] Houaiss dates the Portuguese noun to 1255 from Cunha's slips of the medieval vocabulary.[3] The vernacular records of the 13th century use it for grain and salt: e XXX moyos de pan meyado “and thirty moios of mixed bread-corn” in 1268, and oyto moyos de sal “eight moios of salt” in 1296.[2]
Semantic evolution
In the Middle Ages the moio was a measure of grain, wine and salt, and in the Crónica Troiana a measure of liquids, used hyperbolically for mill moyos de sange “a thousand moios of blood”.[2] Its size varied by province; the dictionaries settled on sixty alqueires, about 828 litres in Lisbon.[14][15][16] Priberam glosses it as what a millstone can grind in one day.[17] It was also a measure of land.[18]
From the measure of sixty alqueires the word came to mean “a set of sixty” in the sale of goods (fruit, melons), and then any sixty things, even years.[16][3] The DLP labels this use regional, and Wiktionary colloquial.[19][1] In Galicia moio is a wine measure of eight olas, a count of 120 roof tiles and a measure of twelve ferrados of grain.[20] Galician notarial books of the 15th century already count tiles by the moyo.[2]

Usage notes
Houaiss and Wikcionário also record a separate Angolan interjection moio “good morning; goodbye”, a 20th-century borrowing from Lunda-Chokwe.[3][23] Wikcionário traces the Chokwe word to a Proto-Bantu noun for “life, spirit, heart”.[23]
