IPA: //ˈbuːləvɑːrd//
KK: /ˈbuləˌvɑrd/
A wide street in a city, usually with trees and landscaping, designed for both vehicles and pedestrians.
We took a leisurely stroll down the boulevard, enjoying the shade of the trees.
Boulevard is derived from the French word 'boulevard', which originally referred to a rampart or fortification (from 'boulevard' meaning a bulwark or a defensive wall). The term evolved to describe a broad street that was often built on the site of these fortifications. Thus, a boulevard is a wide street that may have originally been a defensive structure.
Imagine a wide street that was once a protective wall ('boulevard' means a rampart) — this helps you remember that a boulevard is a broad street.
