stuff

Compared meaning: the substance something is made of (noun).

比较义项：构成事物的材料、物质（名词）。

• material

  Names a specific, identifiable substance (cotton, metal, wood); neutral register, used in both casual and technical contexts, often with 'made from/of'.

  指可以说出具体名称的材料（如棉、金属、木材）；语气中性，口语和专业场合都常用，常与“made from/of”搭配。

  This jacket is made from a soft, warm material.

  这件夹克是用一种柔软保暖的材料做成的。

• stuff 本词

  Vague, informal word for a substance whose exact identity is unknown, unimportant, or not worth naming; sounds casual, even careless in formal writing.

  口语化、笼统的说法，指不知道、不重要或懒得说明具体名称的物质；语气随意，用在正式书面语中会显得不够严谨。

  There's some sticky stuff on the table that I can't identify.

  桌子上有些黏糊糊的东西，我认不出是什么。

Material and stuff both mean the substance something is made from. Material names a specific substance, like cotton or metal, and sounds neutral. Stuff is informal and vague, used when you don't know or don't care about the exact substance.

两者都可以指“做成某物的物质”，但 material 通常指可以说出具体名称的材料，语气中性、正式；stuff 是口语化的笼统说法，用于说不清或不想说清材质时。这里不比较 stuff 表示“东西、随身物品”的义项（如 put your stuff away）。

Compared meaning: eat too much food, greedily (verb).

比较义项：贪婪或过量地吃东西（动词）。

• stuff 本词

  Very informal; almost always reflexive (stuff yourself / your face), suggesting eating fast and without restraint, often in a casual or humorous tone about a big meal.

  非常口语化，几乎总是用于自反结构（stuff yourself／your face），强调吃得又快又毫无节制，常带有随意或诙谐的语气，用来形容一顿大餐。

  We always stuff ourselves at Thanksgiving and regret it later.

  我们感恩节总是把自己吃撑，事后又后悔。

• gorge

  Suggests eating ravenously and rapidly, almost animal-like; typically used with 'on' (gorge on something) or reflexively, in a more vivid or literary way than stuff.

  强调像动物一样狼吞虎咽、吃得又快又猛，常与on连用（gorge on something）或用于自反结构，语气比stuff更生动，略带文学色彩。

  He gorged himself on barbecue until he couldn't move.

  他狼吞虎咽地吃烧烤，直到撑得动弹不得。

• overeat

  Neutral, almost clinical term for consuming more food than the body needs; common in health, diet, and nutrition contexts, without implying greed.

  语气中性、近乎医学化，用来描述摄入食物超过身体所需，常见于健康、饮食或营养语境，不带贪婪的含义。

  Doctors warn that overeating late at night can disrupt sleep.

  医生警告说，晚上吃得过多会影响睡眠。

Stuff, gorge, and overeat all mean to eat too much. Stuff and gorge describe eating fast and greedily, almost always used with yourself, as in stuff yourself. Gorge sounds vivid, almost animal-like. Overeat is neutral, meaning eating more than needed, common in health contexts.

这三个词都表示“吃得过多”，但语气和使用场合不同：stuff和gorge强调狼吞虎咽的动作，且几乎总是与自反代词连用（stuff yourself／gorge yourself），语气更随意或生动；overeat则只是客观描述摄入量超过身体所需，语气中性，常见于健康或饮食语境。这里不比较stuff作名词“物品”的意思，也不比较gorge作名词“峡谷”的意思。
