port

Etymology and origin of the English word port

English has four main words spelled port: the harbour, from Latin portus, the gate or opening, from Latin porta, the bearing, from Latin portāre “to carry”, and the wine, named after Oporto.[1][2][3] The three Latin words are related.[3]

Ultimate origin
Latin (portus)

Etymology

The harbour is inherited from Middle English port, inherited from Old English port (“harbour, haven; town”),[3][1][5] and in Middle English it was reinforced, borrowed from Old French port (“harbour, mountain pass”).[3][1] Both are from Latin portus (“harbour; originally an entrance, a passage”),[3][1] akin to porta (“gate”),[3] from Proto-Indo-European *prtu- (“a going, a passage”), a suffixed form of Proto-Indo-European *per- (“to lead, pass over”).[3] It is related to ford.[1][2] The left side of a ship is probably from the same word, as the side that faced the harbour when the ship was docked,[3][1][2] or from the porthole sense.[5]

Earliest recorded meaning

A harbour: before 899, in Alfred's translation of Orosius,[1] and in the OED from about 893.[6] A town with a harbour is from before 900.[6]

Semantic evolution

A figurative place of refuge is from the early 15th century,[3] and any port in a storm from 1749.[3][6] A port of entry is from 1840, and a port of call from 1810 in Etymonline[3] or 1884 in the OED.[6] The left side of a ship, looking forward, is from the 1540s,[3] about 1544 in Merriam-Webster.[5] On old ships the steering oar was on the right side, so they tied up on the other;[3] the loading hatch was on this side, turned towards the quay.[7] It replaced larboard, which was too easily confused with starboard when shouted in a gale;[7] the change was made official by Admiralty order in 1844 and by a United States Navy Department notice in 1846.[3] Barnhart's first example of the left side is in Manwayring's Seaman's Dictionary (1625–44).[1] The adjective is from 1857.[3]

First attested

Borrowed from
Old French porte via Middle English
Ultimate origin
Latin (porta)

Etymology

The opening is inherited from Middle English porte (“gate”),[3][1][5] borrowed from Old French porte (“gate, entrance”),[3][1] from Latin porta (“city gate, door, passage”),[3][1] akin to portus (“harbour”), from Proto-Indo-European *per- (“to lead, pass over”).[3] Old English also had an occasional port in this sense, from Latin, but the Middle English word seems to be a new borrowing through French.[3][2]

Earliest recorded meaning

A gate, the gate of a town or fortress: about 1300,[3][1] with the surname Port from 1243.[1] The gate of a city or walled town is from the 13th century in Hoad.[2]

Semantic evolution

An opening in the side of a ship, the porthole, is from the mid-14th century;[3][2] in old warships it was the opening through which the cannon were pointed.[3] The medical sense, a place where something enters the body, is by 1908, probably short for portal.[3] In electronics a pair of terminals where a signal enters or leaves a device is from 1953, and in computing a place where signals enter or leave a system by 1979.[3] The verb, to move a program to another computer system, is from 1984, perhaps from the hardware sense, influenced by portable.[5]

Timeline

  • 1243 – the surname Port.[1]
  • c. 1300 – a gate.[3][1]
  • mid-14th century – a porthole.[3]
  • 1908 – in medicine.[3]

Borrowed from

Etymology

The bearing is inherited from Middle English pourt,[1] borrowed from Old French port (“carriage, demeanour”),[3][1] from porter (“to carry”),[3][1] from Latin portāre (“to carry, bear”),[3][1] from Proto-Indo-European *per- (“to lead, pass over”).[3][1] The verb, “to carry”, is borrowed from French porter, from the same Latin verb,[3][1] which is also the source of deport, export, import, report and support.[3]

Earliest recorded meaning

Bearing, carriage, mien: about 1300 in Etymonline,[3] probably before 1300 in Guy of Warwick according to Barnhart.[1]

Semantic evolution

External appearance is from about 1400, and the now archaic “state, style of living” from the 1520s.[3][2] The verb, “to carry, bring”, is from the 1560s,[3][1] and the military sense, to carry a rifle diagonally across the body, from the 1620s.[3] portly, once “of dignified bearing”, is from the 16th century.[2]

Timeline

  • c. 1300 – bearing, demeanour.[3][1]
  • c. 1400 – appearance.[3]
  • 1520s – style of living.[3]
