比较义项：建造，建立（动词）。

• build

  The everyday, general word for putting something together; used in casual speech for almost anything, from houses to forts, and often extends to abstract things like relationships.

  日常、通用的词，口语中几乎可用于任何搭建的东西，从房屋到堡垒都行，也常引申用于抽象事物，如建立关系。

  My uncle built a blanket fort in the living room for the kids.

  我叔叔在客厅给孩子们搭了一个毯子堡垒。

• construct 本词

  A more formal, technical word, typical of engineering or official writing; usually describes carefully planned, often large or complex structures, and rarely used for casual, small, everyday things.

  更正式、更技术性的词，常见于工程或官方文书，通常描述经过精心规划、往往规模较大或复杂的结构，很少用于随意的日常小物件。

  Engineers plan to construct a new dam using reinforced concrete.

  工程师计划用钢筋混凝土建造一座新的大坝。

Build and construct both mean putting materials together to make something. Build is common and everyday, used for almost anything. Construct is more formal, used in writing or engineering, for bigger, complex structures. Build's meaning of building relationships is not compared here.

build和construct都指把材料组合搭建成实物，但build更口语、更常用，几乎什么东西都能用；construct更正式，多见于书面或工程、建筑类语境，且常搭配较大或较复杂的结构。这里不比较build用于抽象事物（如建立关系、信心）的引申义。

Compared meaning: an abstract idea (noun).

比较义项：概念（n.）。

• concept

  The plain, everyday word for an abstract idea; neutral in register and usable in almost any context, often in phrases like 'basic concept' or 'key concept'.

  最普通、最日常的词，指抽象的想法；语气中性，几乎任何场合都能用，常用于“basic concept”（基本概念）、“key concept”（关键概念）等搭配。

  The concept of zero was a major breakthrough in early mathematics.

  零的概念是早期数学史上的一项重大突破。

• construct 本词

  A more formal, academic word, common in social science; suggests an idea that is deliberately built up or theorized rather than simply observed, as in 'social construct'.

  语气更正式、偏学术，常见于社会科学领域；表示某个想法是被人为建立或理论化出来的，而不是单纯观察到的，如“social construct”（社会建构）。

  Sociologists argue that race is largely a social construct.

  社会学家认为，种族在很大程度上是一种社会建构。

• conception

  Formal or literary in tone; emphasizes one particular person's own mental picture or understanding of something, often phrased as 'someone's conception of X'.

  Every artist has a different conception of what beauty really means.

  每位艺术家对“美”的真正含义都有不同的理解。

Concept, construct, and conception all mean an abstract idea, but tone differs. Concept is the plain, everyday word, as in 'basic concept'. Construct is more formal, suggesting an idea built through theory, as in 'social construct'. Conception is formal, emphasizing one person's understanding of something.

这三个词在“概念、想法”这个意思上很接近，但语气和使用场合不同：concept 最常用、最中性；construct 偏学术/理论化，常用于“社会建构”等固定搭配；conception 强调某人自己对某事物的理解或看法，语气更正式。这里不比较 construct 的动词义“建造”（如 construct a bridge），也不比较 conception 的“怀孕、受孕”义。
