new

Compared meaning: new or different, from mild to extreme (adjective).

比较义项：新的、与以往不同的（程度从「新近出现」到「彻底颠覆」不等）（形容词）。

• new 本词

  The mildest of the four; simply means something has just appeared or been acquired, with no implication of being different or extreme. Common with ordinary nouns like a job, apartment, or idea.

  四词中语气最弱，只表示某事物刚刚出现或刚刚获得，并不暗示与以往不同或程度极端，常与工作、公寓、主意等普通名词搭配。

  The company hired new staff for the summer season.

  公司为暑期招聘了新员工。

• fresh

  Emphasizes novelty and a marked difference from what came before, often paired with words like idea, approach, or start; stronger than 'new' but far weaker than 'radical'.

  强调新颖、与以往明显不同，常与主意、方法、开始等词搭配；语气比new强，但比radical弱得多。

  After the divorce, he moved abroad for a fresh start.

  离婚后，他搬到国外，开始了全新的生活。

• radical

  Describes ideas or changes that are extreme and go against convention, often controversial or ideological; much stronger than 'fresh', not necessarily total transformation like 'revolutionary'.

  形容极端、违背常规的想法或变革，常带有争议性或意识形态色彩；语气比fresh强得多，但不一定像revolutionary那样是彻底的变革。

  The senator proposed radical reforms to the tax system.

  这位参议员提出了对税收制度的激进改革。

• revolutionary

  Describes a change so complete and dramatic that it transforms an entire field or system, often used positively for breakthroughs; the strongest of the four.

  形容彻底、戏剧性的变化，能改变整个领域或体系，常用于褒义地形容突破性成果；是四词中语气最强的。

  The new vaccine was hailed as a revolutionary medical breakthrough.

  这款新疫苗被誉为革命性的医学突破。

New, fresh, radical, and revolutionary all describe something different, but the strength differs. New is mildest, meaning something recently appeared. Fresh means noticeably different, stronger than new. Radical means extreme change against convention. Revolutionary means a complete, dramatic change, the strongest of all.

这四个词都能形容「新颖、与以往不同」的事物或变化，但程度不同：new语气最弱，只表示新近出现；fresh强调新颖别致，比new更强；radical和revolutionary都表示彻底、极端的改变，语气最强，其中revolutionary更强调「划时代、颠覆性」。这里不比较new表示「崭新、未曾使用过」的意思，也不比较fresh表示「新鲜（食物未变质）」的意思，不比较radical在数学中表示「根」或作名词表示「激进分子」的意思，也不比较revolutionary表示「与政治革命相关」的意思。

Compared meaning: new, fresh, or not seen before (adjective).

比较义项：新的、新颖的（形容词）。

• new 本词

  The plainest and most general word for something not previously known or experienced by the person; carries no special sense of creativity or formality and fits almost any everyday context.

• fresh

  Highlights that something is different from what came before and feels renewing or invigorating; commonly collocates with words like eyes, perspective, approach or start rather than inventions.

  强调与以往不同、带来焕然一新的感觉；常与“eyes（眼光）”“perspective（视角）”“approach（方法）”“start（开始）”等词搭配，而不用于形容发明。

  A fresh pair of eyes often spots problems the team overlooked.

• novel

  A more formal word stressing that something is unlike anything known before; typical in academic, scientific or technical writing about new methods, inventions or discoveries.

New, fresh, original, and novel all mean something not experienced before. New is the plainest general word. Fresh highlights a refreshing difference, often in perspective. Original stresses creativity, not copied from others. Novel is more formal, common in academic writing, for something unlike anything before.

这四个词都能表示“新”，但侧重点不同：new 最平实、最通用，泛指此前不知道或未经历过的事物；fresh 强调与以往不同、令人耳目一新；original 强调有创意、非抄袭模仿；novel 语气更正式，强调前所未有。此处不比较 new 的“全新未用过”之义、fresh 的“新鲜（食物）”之义，以及 original 的“最初的、原件的”之义。
