• boom

  Boom describes a sudden, often short-lived surge, especially in economic activity, business, or demand; it emphasizes speed and scale of increase rather than sustained health or quality.

  boom指突然、往往短暂的激增，尤指经济活动、商业或需求方面；强调增长的速度和规模，而非持续的健康或质量。

  Demand for electric cars boomed after fuel prices doubled last year.

  去年燃油价格翻倍后，电动汽车的需求迅速激增。

• thrive

  Thrive emphasizes vigorous, healthy growth, often under specific or even difficult conditions, and is common for living things as well as people or organizations enduring hardship well.

  thrive强调在特定甚至艰难条件下依然健康、旺盛地成长，常用于生物，也可用于在逆境中表现良好的人或组织。

  The cactus continued to thrive even after weeks without water.

  即使几周没有浇水，这株仙人掌依然茁壮成长。

• flourish 本词

  Flourish suggests a broader, more formal or literary sense of prospering and developing fully over time, often used for cultures, arts, careers, or businesses reaching a high point rather than describing a sudden spike.

  flourish带有更宽泛、较正式或文学化的意味，指长期全面地繁荣发展，常用于文化、艺术、事业或企业达到鼎盛状态，而不是描述突然的激增。

  The local arts scene flourished after the old theatre was restored, drawing new galleries to the area.

  旧剧院修复后，当地的艺术圈蓬勃发展，吸引了新的画廊入驻这一地区。

Boom, thrive, and flourish can all mean to grow successfully, but the focus differs. Boom means a sudden, often short increase, especially in business. Thrive means healthy, strong growth, often under hard conditions. Flourish is more formal, meaning to prosper, for culture or careers.

这三个词都可表示“成功地成长、发展”，但语气和适用范围不同：boom侧重经济或商业活动的迅猛激增，常是短期现象；thrive侧重健康茁壮的持续成长，常见于动植物或身处逆境中的人和组织；flourish则语气较正式，强调长期、全面的繁荣，常用于文化、艺术或事业。这里不比较boom作为“隆隆声”的义项，也不比较flourish作为“挥舞（炫耀地舞动）”的义项。

Compared meaning: to wave something in the air (verb).

比较义项：挥舞（动词）。

• flourish 本词

  means to wave something about in a showy, triumphant or attention-seeking way, with no hint of threat; often used with things like tickets, certificates or trophies

  指炫耀性地挥动某物，带有得意或引人注目的意味，没有威胁的意思；常与车票、证书、奖杯等搭配使用

  She flourished her winning ticket in the air for everyone to see.

  她把中奖的彩票在空中挥舞，让每个人都看见。

• brandish

  means to wave something around aggressively as a threat, almost always a weapon or weapon-like object, to intimidate someone

  指带有威胁性地挥舞某物，几乎总是武器或类似武器的东西，目的是恐吓他人

  The robber brandished a knife and demanded all the money.

  劫匪挥舞着一把刀，要求交出所有的钱。

Both words mean to wave something in your hand, but the tone differs. Brandish suggests a threatening, aggressive wave, usually of a weapon. Flourish suggests a showy, proud wave, like performing, with no threat. This does not compare flourish meaning to prosper or grow well.

两词都指挥动手中之物，但语气强弱不同：brandish 带有威胁、挑衅的意味，常与武器搭配；flourish 则是炫耀性地挥动，带表演或得意的意味，并无威胁之意。这里不比较 flourish 的“繁荣，茂盛”义。
