IPA: /ˈbaɪˌstriːt/
KK: /ˈbaɪˌstrit/
A smaller road that is connected to a main road, often used for local traffic.
The restaurant is located on a quiet bystreet away from the busy main road.
Bystreet → The word is formed from "by" (from Old English "bi", meaning near or beside) and "street" (from Old English "straet", meaning a paved road or path). A bystreet refers to a street that is located beside or near a main street.
Think of a street that is 'near' ('by') another street — that's what a bystreet is.
