primitive

Compared meaning: primitive, simple and undeveloped (adjective).

比较义项：原始的，未开化的（形容词）。

• primitive 本词

  The neutral, everyday word for an early or simple stage of development; used freely in ordinary, scientific, and historical writing without negative judgment.

  primitive 是描述早期或简单发展阶段的中性常用词，可自由用于日常、科学和历史类文本中，不带负面评价。

  Early humans carved primitive tools out of flint and bone.

  早期人类用燧石和骨头雕刻出原始的工具。

• rude

  A dated, literary word for the same idea, almost always describing simple huts, shelters, or crafts; elsewhere rude usually means impolite, so this sense is easy to miss.

  rude 在这个意义上是过时的、文学性的说法，几乎总是用来描述简陋的小屋、住所或手工制品；在其他语境中 rude 通常指“粗鲁的”，因此这个原始义很容易被忽略。

  The explorers slept in rude huts built from branches and mud.

  探险者们睡在用树枝和泥巴搭建的原始小屋里。

Primitive and rude are close in meaning here. Primitive is the neutral, everyday word for an early, simple stage of development. Rude here is old-fashioned and literary, describing simple huts or shelters. This does not compare rude's everyday meaning, 'impolite'.

这两个词在“原始的”这个意义上很接近，但语体和常见程度不同：primitive 是描述早期发展阶段的中性常用词；rude 在这个意义上是过时的、文学性的说法，多与 primitive 或 crude 连用。这里不比较 rude 更常见的“粗鲁的，无礼的”这一义项。
