Origins

Meanings 1, 8, 11–12, 15–16

From Old English port, borrowed from Latin portus ("port, harbour"), and ultimately from a Proto-Indo-European noun *pértus ("crossing"), making it a distant relative of ford. The directional sense, seen since at least the 1500s, comes from ancient vessels having the steering oar on the right, so they had to moor with their left sides facing the dock.
