Forms

porto m (plural portos, metaphonic)[1] The plural portos is pronounced with an open /ɔ/.[1][2] The older spelling pôrto is also recorded.[1]

Etymology

It is inherited from Latin portus (“passage, entrance; harbour”), written Old Galician-Portuguese porto in the oldest texts.[3][4][1][5]

The same Latin word is Galician porto, Spanish puerto, Catalan port, French port and Italian porto.[6][1] Spanish and Portuguese also use the word for a mountain pass, a sense that Corominas traces in Spanish to a pre-Latin Indo-European form of the same root.[7]

The Latin word goes back to *portus, from Proto-Indo-European *pértus (“crossing”), and its cognates include the English word ford and fjǫrðr (“fjord”); the Latin porta (“gate”) belongs to the same family.[1]

Earliest recorded meaning

Houaiss's first date, 919, comes from a Latin charter.[3] In the 13th century the Cantigas de Santa Maria already use the word figuratively of the Virgin, tu que es porto u arriban os coytados “you who are the harbour where the troubled come to land”, and literally of o porto das aguas mui fondas “the harbour of very deep waters”;[8] prender porto meant “to put into port”.[8] A cantiga d'escarnho has porto for a place where a river is crossed.[9]

Semantic evolution

Viterbo notes the many places named Porto and Portela from the 10th century, where the word meant a gate, a gorge or a passage over land.[10] Morais gives first “a place that gives passage over land”, with portagem, the toll collected at such passes, and only then the harbour.[11] These land senses are archaic now, and the harbour, a port city and a place of refuge are the current ones.[3][12] In Portugal the word also names a gap in the fence of a property, and in Trás-os-Montes a narrow crossing of a stream.[13][14] The city of Porto gave its name to the fortified wine, and porto alone means port wine from Figueiredo's dictionary of 1899.[3][15]
