gone

Compared meaning: no longer existing or not obtainable (adjective).

比较义项：不再存在／无法获得（adj.）。

• gone 本词

  Informal and blunt; implies something has disappeared, been used up, or a person has left, with no reason given; common with food, money, or people leaving a place.

  语气非正式且直接；暗示某物已经消失、用完，或某人已经离开，且不说明原因；常用于食物、金钱或人离开某地的情况。

  I checked the fridge, but the milk was already gone.

  我看了看冰箱，发现牛奶已经没了。

• unavailable

  More formal and neutral; focuses on something currently not obtainable, accessible, or reachable, without suggesting it disappeared or was used up.

  语气更正式、更中性；强调某物目前无法获得、无法使用或联系不到，并不暗示它已经消失或被用完。

  The doctor is unavailable until next Monday.

  医生要到下周一才有空。

Gone and unavailable both describe something you cannot get, especially when sold out. Gone is informal, meaning something has disappeared or been used up. Unavailable is more formal, meaning something cannot currently be obtained or reached. Not compared: gone meaning someone has died.

这两个词都可以用来说“东西没了、拿不到了”，尤其是售罄这类语境；但gone语气更口语直接，强调东西已经消失或用完，unavailable更正式中性，强调目前无法获取、使用或联系上，并不暗示东西已经不在了。这里不比较gone表示“（委婉说法）已故、去世”的意思。

Compared meaning: no longer alive, dead (adjective).

比较义项：已经死去、不再活着（形容词）。

• dead

  The plain, blunt, everyday word for no longer alive; used for people, animals or plants; works both before a noun and after a linking verb; carries no softening tone.

  最普通、直白的日常用词，指不再存活，可用于人、动物或植物；既能放在名词前，也能跟在系动词后面；没有委婉语气。

  The doctors confirmed that the patient was already dead on arrival.

  医生确认这名病人送到时已经死亡。

• late

  A euphemistic, slightly formal word used ONLY right before a name or a family noun to mean someone who has died; it cannot follow a linking verb with this meaning.

  一个委婉、略正式的词，只能直接放在人名或亲属称谓前面，表示某人已经去世；不能跟在系动词后面表达这个意思。

  My late grandmother used to bake bread every Sunday morning.

  我已故的祖母以前每个星期天都会烤面包。

• gone 本词

  A soft, informal, comforting euphemism, almost always used after a linking verb like "be" or "have been"; it feels gentler than dead and is common in spoken, emotional contexts.

  一个柔和、口语化、带安慰意味的委婉说法，几乎总是跟在系动词（如 be、have been）后面；语气比 dead 更温和，常见于口语和情感场合。

  Her father has been gone for almost ten years now.

  她父亲已经去世将近十年了。

• deceased

  A formal, official word typical of legal, medical or obituary language; often used before a noun or as a noun phrase ("the deceased"); it sounds cold and out of place in casual speech.

  一个正式、公文化的词，常见于法律、医学或讣告语言；常放在名词前，或本身作名词短语（“the deceased”意为“死者”）；在日常口语中使用会显得冷漠、不合场合。

  The deceased man's family requested a private funeral service next week.

  这位已故男子的家人要求下周举行一场私人葬礼。

Dead, late, gone, and deceased all mean no longer alive, but tone and grammar differ. Dead is plain, used for people or animals. Late goes only right before a name, meaning that person died. Gone is soft, used mainly after 'be'. Deceased is formal.

这几个词都表示“已经死去、不再存活”，但语气、正式程度和语法用法差别很大，中国学习者容易用错场合。这里不比较 dead 表示“（电池等）没电的”义项，late 表示“迟到的”义项，也不比较 gone 表示“离开了、用完了”等义项。
