dead

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

比较义项：已经死去、不再活着（形容词）。

• dead 本词

  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

  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。

Compared meaning: not active, not working (adjective).

比较义项：不活跃的／闲置的（形容词）。

• dead 本词

  Dead describes something completely without power or function, usually implying it has stopped working entirely, not just paused; common with batteries, phones, and electronic devices.

  dead强调某物完全失去电力或功能，通常表示彻底停止运作而非暂时暂停，常用于电池、手机等电子设备。

  The old phone battery is completely dead and won't charge.

  这块旧手机电池已经完全没电了，充不进去。

• idle

  Idle describes a machine, engine, or system that is currently not running or engaged, but is capable of starting again soon; often implies a temporary pause during use.

  idle表示机器、引擎或系统目前没有运转或投入使用，但随时能够重新启动，通常指使用过程中的暂时停顿。

  The car engine was idle while we waited at the light.

  我们在等红灯时，汽车引擎处于闲置状态。

• inactive

  Inactive describes something like an account, membership, or system that has not been used or has not operated for a period of time; neutral in tone, emphasizing duration rather than power state.

  inactive表示账户、会员资格或系统在一段时间内未被使用或未运作，语气中性，强调“未使用的时长”而非动力状态。

  His social media account has been inactive for almost a year.

  他的社交媒体账户已经闲置将近一年了。

All three describe something not active. Dead means completely without power, usually stopped entirely, common with batteries. Idle describes a machine not currently running, but able to start again soon. Inactive describes an account not used for a period of time, neutral in tone.

dead、idle和inactive在“不活跃的／闲置的”这一义项上意思相近，但语气强弱和使用场合不同：dead语气最强，强调彻底失去功能；idle强调暂时停止运转，随时可恢复；inactive语气中性，强调一段时间未被使用。这里不比较dead的“已死的，无生命的”义，也不比较idle的“懒散的，无所事事的”义。

Compared meaning: completely, totally (degree adverb).

比较义项：完全地，彻底地（程度副词）。

• dead 本词

  "Dead" is a casual intensifier placed directly before an adjective or past participle only (as in "dead tired" or "dead certain") — it never modifies a verb, and sounds informal, mainly British.

  “dead”是口语化的程度副词，只能直接放在形容词或过去分词前（相当于“很疲惫”“很确定”这类说法），从不修饰动词，语气随意，主要见于英式英语。

  After the night shift, I was dead tired and fell asleep on the sofa.

  上完夜班后，我累得要命，倒在沙发上就睡着了。

• absolutely

  "Absolutely" is neutral in tone and typically modifies verbs that express opinion or feeling (as in "absolutely love") or extreme, ungradable adjectives, rather than ordinary gradable ones like "tired."

  “absolutely”语气中性，通常修饰表达观点或情感的动词（相当于“非常喜欢”这类说法），或修饰极端的、不可分级的形容词，而不是像“tired”这样的普通可分级形容词。

  I absolutely love the smell of fresh coffee in the morning.

  我早上真的非常喜欢新鲜咖啡的香味。

• perfectly

  "Perfectly" means "completely, without any flaw," and is mainly used to describe how smoothly something goes or how adequate or normal a state is (as in "perfectly fine" or "worked out perfectly").

  “perfectly”意为“完全没有瑕疵”，主要用来描述事情进行得有多顺利，或某种状态是否正常、足够（相当于“完全没问题”“进行得完美无缺”这类说法）。

  The recipe worked out perfectly, and the cake rose exactly as it should.

  这个食谱做得完美无缺，蛋糕正好按预期发起来了。

• utterly

  "Utterly" is a stronger, more formal intensifier used almost only before negative or extreme adjectives (as in "utterly exhausted" or "utterly ridiculous"), emphasizing an extreme, usually undesirable state.

  “utterly”语气更强、更正式，几乎只用在消极或极端的形容词前（相当于“彻底精疲力尽”“荒谬至极”这类说法），强调一种极端、通常不好的状态。

  She was utterly exhausted after the long hiking trip.

  长途徒步之后，她彻底精疲力尽了。

All four mean completely. Dead is casual, before an adjective ('dead tired'). Absolutely is neutral, before verbs or adjectives. Perfectly means without flaw, for normal states. Utterly is stronger, before negative adjectives. Dead can mean 'not alive', and absolutely can mean 'yes'; not compared here.

这四个词在此都表示“完全、彻底”，但语气和用法不同：dead最随意，只能直接修饰形容词或分词；absolutely语气中性，常修饰动词或极端形容词；perfectly强调“毫无瑕疵”，多用于描述顺利、正常的状态；utterly语气更强、偏正式，几乎只用在消极或极端的形容词前。这里不比较dead作形容词表示“死的”的用法，也不比较absolutely单独使用表示“当然、没错”的用法。
