語源
英語の原文（Wiktionary）
From Middle English sterbord, stere-bourd, stere-burd, from Old English stēorbord, from Proto-West Germanic *steurubord, equivalent to steer + board (“side (of a ship)”), referring to ancient ships with the steering oar set to the right (to accommodate right-handed crew). Ships had to dock on their left (port) side because the steering oar on the right would get in the way, which is how the left became known as the port side.
