wide

Compared meaning: covering a large area (adjective).

比较义项：面积广、范围大（形容词）。

• wide 本词

  Wide focuses on the breadth of something from side to side, and is the standard word for rivers, roads, and open spaces — not for general objects like a house or a dog.

  wide 着重指某物从一侧到另一侧的宽度，是描述河流、道路和开阔空间的标准用词，不适合用来形容房子或狗等普通物体。

  The new highway is wide enough for four lanes of traffic.

  这条新高速公路宽到可以容纳四条车道。

• extended

  Extended describes something enlarged or stretched beyond its original or usual scope, often used for families, networks, or time periods rather than plain physical size; it is more formal than the other three words.

  extended 指某事物被扩大或延伸到超出原有或通常的范围，常用于家庭、网络或时间段，而不是单纯的物理大小；比另外三个词更正式。

  In many cultures, the extended family includes grandparents, aunts, and uncles.

  在许多文化中，大家庭包括祖父母、姑姑和叔叔。

• great

  Great is an emphatic, somewhat literary word for grand or impressive size, typically used for expanses like forests, plains, or oceans; outside this sense it usually just means excellent.

  great 是一种带有文学色彩、语气较强的说法，形容宏大或令人印象深刻的规模，常用于森林、平原、海洋等广阔景象；在这一意义之外，great 通常只表示“极好的”。

  A great forest once covered this entire region.

  一片广袤的森林曾经覆盖了这整个地区。

• big

  Big is the plain, everyday word for large size, usable for almost anything from objects to feelings, with no special register — the most common and neutral choice in casual speech.

  big 是最普通、最日常的“大”，几乎可以用来形容任何事物，从物体到感受都适用，没有特殊语域色彩，是口语中最常见、最中性的选择。

  They live in a really big house with five bedrooms.

  他们住的房子真的很大，有五间卧室。

Wide, extended, great, and big can all describe a large area. Wide means broad, used for rivers or roads. Extended means enlarged beyond its usual scope, often families or networks. Great is emphatic and literary, for forests or oceans. Big is the plain, everyday word.

这四个词都可以表示面积大、范围广，但语气和适用范围不同：wide 侧重物理宽度，big 最口语化，extended 更正式，常见于家庭、网络等抽象范围，great 则带有文学色彩、语气更强烈。这里不比较 great 表示“极好的”的用法，也不比较 extended 表示（时间上）延长的用法。
