roast

Compared meaning: cooked and ready to eat (adjective).

比较义项：（食物）做熟的、可以吃了（形容词）。

• done

  A general result word: says the food has finished cooking and is ready to eat, without saying how it was cooked (boiled, fried, roasted, etc.). Very common in casual speech, often as 'be done'.

  这是一个表示结果的通用词：只说明食物已经做熟、可以吃了，并不说明是用什么方法做的（煮、炸、烤等）。在口语中很常见，常用 be done 这种结构。

  Check the chicken with a thermometer to make sure it's done before you serve it.

  用温度计检查一下鸡肉，确保端上桌之前它已经熟了。

• roast 本词

  Describes food cooked slowly in an oven or over a fire, usually a whole piece of meat or vegetables; it names the cooking method itself, not just the result. Typically used before a noun, like 'roast chicken'.

  指用烤箱或明火慢慢烤熟的食物，通常是整块的肉或蔬菜；它说明的是烹饪方法本身，而不只是熟了这个结果。通常放在名词前使用，比如 roast chicken（烤鸡）。

  On Sundays my family usually has roast chicken with potatoes.

  我家周日通常吃烤鸡配土豆。

Done and roast both describe cooked food. Done says food has finished cooking, without saying how. Roast means cooked in an oven or fire, often a whole piece of meat, usually before a noun. Done can also mean 'finished a task'; not compared here.

这两个词都表示食物已经加热到可以食用的状态，但 roast 特指用烤箱或明火烘烤这种烹饪方式，而 done 只说明“熟了”这个结果，不说明是怎么做熟的。这里不比较 done 的其他常见义项，例如“完成了（某项任务）”。
