Compared meaning: having little or no light (adjective).

比较义项：形容光线昏暗、缺乏亮度（形容词）。

• dark

  The most general and strongest word for lack of light; can describe total darkness in a place, unlike words tied to a specific light level or time of day.

  语气最强、最通用的“黑暗”一词，可以指完全没有光线的状态，不像其他词那样限定具体的光线程度或时间段。

  The basement was completely dark; I couldn't see my hand.

  地下室完全漆黑一片，我连自己的手都看不见。

• twilight

  Refers specifically to the dim light just before sunrise or after sunset, tied to that time of day rather than describing darkness in general.

  特指日出前或日落后那段微弱光线的时段，与具体的时间点相关，而不是泛指昏暗。

  We watched the sky turn a soft orange at twilight, just after sunset.

  日落后不久的暮光时分，我们看着天空变成柔和的橙色。

• dim 本词

  Describes a weak or faint light, often from a specific source, not the total absence of light; commonly used for lamps, rooms or views.

  形容微弱、不明亮的光线（常指某个光源），而不是完全没有光线；常用来形容灯光、房间或视野。

  The dim streetlight barely lit the narrow alley behind our house.

  昏暗的路灯几乎照不亮我们家后面那条狭窄的小巷。

• gloomy

  Dark in a way that also suggests a sad or depressing mood, often used for weather, skies or atmospheres rather than just light level.

  形容昏暗中带有令人沮丧、忧郁的情绪色彩，常用来形容天气、天空或氛围，而不仅仅是光线程度。

  The gloomy grey sky made the whole afternoon feel sad and heavy.

  阴沉灰暗的天空让整个下午都显得压抑而沉闷。

Dark, twilight, dim, and gloomy all describe weak or missing light. Dark is the strongest and general. Twilight is the faint light before sunrise or after sunset. Dim is a weak light from a source, like a lamp. Gloomy adds a sad feeling to darkness.

这几个词都能形容光线不足或昏暗的状态，但侧重点、程度和使用场合各不相同：dark 语气最强最通用，twilight 专指黎明或黄昏的微光时段，dim 强调光源微弱而非完全无光，gloomy 则常带有令人沮丧的情绪色彩。这里不比较 dark 表示“肤色深”或“秘密的”之义，也不比较 gloomy 表示“悲观、沮丧”心情的比喻义，以及 twilight 表示“（事业等的）衰落期”的比喻义。

Compared meaning: unclear or hard to see (adjective).

比较义项：模糊不清、难以看清或辨认（形容词）。

• faint

  Faint describes something weak in intensity — a sound, smell, light or feeling — barely strong enough to notice, and can apply to senses other than sight.

  faint 表示强度微弱——声音、气味、光线或感觉都可以是faint——弱到几乎无法察觉，而且不只用于视觉。

  A faint smell of smoke drifted through the hallway, but no one could tell where it came from.

  一股淡淡的烟味飘过走廊，但没有人知道它是从哪里来的。

• fuzzy

  Fuzzy describes blurred or indistinct edges and details — a picture, signal or memory — focusing on a lack of sharpness rather than weak light.

  fuzzy 表示轮廓或细节模糊不清——如图片、信号或记忆——强调的是不清晰，而不是光线弱。

  The security camera footage was too fuzzy to identify the driver clearly.

  监控录像太模糊了，根本看不清司机的样子。

• dim 本词

  Dim describes weak or low light specifically — a room, lamp or the sky — and is not normally used for sounds, smells or shapes.

  dim 专门表示光线暗淡——如房间、灯或天空——通常不用来形容声音、气味或形状。

  He switched on a dim lamp so he wouldn't wake the baby.

  他打开了一盏昏暗的灯，这样就不会吵醒婴儿了。

• shadowy

  Shadowy describes a person, place or shape that is hard to see because of shadow or darkness, or figuratively something mysterious and hard to understand.

  shadowy 表示因阴影或黑暗而难以看清的人、地方或形状，也可以引申表示神秘、难以理解的事物。

  A shadowy figure lurked near the parking garage, and nobody dared to approach him.

  一个模糊的人影在停车场附近徘徊，没有人敢靠近他。

Faint, fuzzy, dim, and shadowy all mean unclear or hard to see. Faint means weak in intensity. Fuzzy means blurred or indistinct, like a picture. Dim means weak light, like a lamp. Shadowy means hard to see in shadow. Other senses are not compared here.

这几个词都能表示“模糊、不清楚”，但侧重点不同：faint 强调强度微弱（声音、气味、光线等都可以是faint）；fuzzy 强调轮廓或细节不清晰（如照片、记忆）；dim 专指光线暗淡；shadowy 强调因阴影而难以看清，也可引申为“神秘难懂”。这里不比较 faint 表示“快要晕倒的”、fuzzy 表示“毛茸茸的”、dim 作动词“使变暗”，以及 shadowy 字面“多阴影的”等其他用法。
