IPA: //ˈbaɪroʊd//
KK: /ˈbaɪroʊd/
A small or less important road, often used for local traffic rather than main routes.
We took a byroad to avoid the heavy traffic on the highway.
Byroad → The word is formed from "by" (from Old English "bi", meaning near or beside) and "road" (from Old English "rād", meaning a way or path). A byroad refers to a road that is near or beside a main road, often a secondary or less traveled path.
Think of a road that is 'near' ('by') another main road — that's why a byroad is a secondary path.
