bush

Compared meaning: a shrub, a low woody plant (noun).

比较义项：灌木（名词）。

• shrub

  More formal or technical word, typical of gardening books, landscaping plans, or botanical descriptions; sounds neat and deliberately planted.

  更正式或专业的用词，常见于园艺书籍、景观设计或植物学描述中；给人一种整齐、经过刻意栽种的感觉。

  We planted a small shrub near the front door last weekend.

  上周末我们在前门附近种了一株小灌木。

• bush 本词

  More common, everyday word; often sounds thicker or wilder, and can describe something growing on its own without careful planning.

  更常见、更口语化的用词；常给人一种更茂密或更野生的感觉，也可以形容自然生长、无人精心打理的植物。

  A small bird was hiding inside the bush.

  一只小鸟藏在灌木丛里。

Both words name a small, woody plant with many branches. Shrub sounds more formal, typical of gardening books. Bush sounds more casual, and often suggests something thicker or wilder. Bush can also mean wild, uncultivated land; that meaning is not compared here.

这两个词都指矮小、多枝干的木本植物，日常都可使用，但 shrub 更书面、常用于园艺或正式描述，bush 更口语化、更常见于日常说法，形态上也常显得更蓬乱茂密。这里不比较 bush 表示“灌木丛、荒野”的义项。
