boulevard

Compared meaning: a wide street (noun).

比较义项：宽阔的街道（名词）。

• avenue

  A general term for a wide street; it does not necessarily have trees and is commonly used in street names (e.g. Fifth Avenue), without boulevard's scenic, tree-lined connotation.

  泛指宽阔的街道，不一定种有树木，常用于街道名称中（如第五大道），不带有 boulevard 那种林荫、景观优美的意味。

  Fifth Avenue is famous for its shops, not for rows of trees.

  第五大道以商店闻名，而不是因为道路两旁种满了树。

• boulevard 本词

  Specifically suggests a wide, grand street lined with trees or a planted median, giving it a scenic, often more upscale feel than a plain avenue.

  特指宽阔气派、两旁种有树木或带有绿化带的大道，给人一种比普通 avenue 更具景观感、更高档的感觉。

  The boulevard's grassy median is lined with palm trees for miles.

  这条林荫大道中央的草地绿化带两旁种满了棕榈树，绵延数英里。

Both mean a wide street. Avenue is general and need not have trees, often used in street names like Fifth Avenue. Boulevard suggests a grand street lined with trees or a planted middle strip. Avenue can also mean a method; not compared.

这两个词都指宽阔的街道，容易混淆：boulevard 通常暗示种有树木或带有中央绿化带的大道，显得更气派、更具景观感；avenue 是更通用的说法，不一定种树，也常用于街道命名（如第五大道）。这里不比较 avenue 表示「途径、方法」这一引申义。
