比较义项：夜晚／黑暗（尤指天黑以后的时间）（名词）。

• night 本词

  A countable time period, the whole span from sunset to sunrise; used with 'at/during/last night' and to describe the sky, weather, or events happening then.

  指从日落到日出的一整段可数的时间，常与 at/during/last night 连用，也用来描述那段时间里的天空、天气或发生的事。

  I couldn't sleep at all last night because of the noise outside.

  昨晚外面太吵，我根本没睡着。

• dark

  An uncountable noun for the state of darkness itself, not a time span; used with 'before/after dark' and 'in the dark', focusing on lack of light rather than the clock.

  作名词时指“黑暗”这一状态本身，是不可数名词，而非一段时间；常与 before dark、after dark、in the dark 连用，强调光线的缺失，而不是具体的时间点。

  Please come home before dark, it's not safe outside after that.

  请在天黑之前回家，那之后外面不安全。

Night and dark relate to the time after sunset. Night is a countable time period, as in 'at night' or 'last night'. Dark is uncountable, the state of darkness, not a time span, as in 'before dark'. Dark as an adjective is not compared here.

night 指从日落到日出的这段时间，是一个可数、有边界的时间段，常用于 at night、last night、during the night 等表达；dark 作名词时指“黑暗”这一状态，不可数，强调光线的缺失，常见于 before dark、after dark、in the dark 等短语，不特指某一整夜的时间跨度。这里不比较 dark 作形容词时“黑暗的、深色的、秘密的”等其他意思。
