語源 2

Likely a borrowing from Dutch bakboord (“portside”) or from Middle Low German backbort, bakbōrt (“portside”). 古期英語 bæcbord (“larboard, portside”) did not survive (in that form) into 中期英語; Scottish texts of the 1500s have forms like bawbord, baburd and babord, possibly borrowed from French bâbord; later texts with Scots backburd, backber may have borrowed it from Old Norse bakborði (“portside”). Cognate with West Frisian bakboard (“portside”), German Backbord (“portside”), Danish bagbord (“portside”).

名詞

   • 2014, Jeff Bredenberg, The Dream Vessel:

     But the gangplank was no longer in place. It had folded itself in half and clamped into storage position, becoming part of the starboard rail. Big Tom peered over the rail and saw nothing but sea. All around. Starboard, backboard, forward, aft.
