net

Compared meaning: material with crossed threads and holes (noun).

比较义项：由交叉的线或丝织成、带有孔洞的网状材料（名词）。

• net 本词

  Net names a finished object, often with a handle or frame, used to catch, hold or block things — the classic tool a fisherman or player uses, not just the raw material.

  net通常指一件成型的工具或物品（常带手柄或框架），用来捕捉、盛装或阻挡东西，比如渔夫或球员用来捕鱼、拦球的网，强调的是“工具”，而不只是材料本身。

  She used a small net to catch the butterfly fluttering near the flowers.

  她用一个小网去抓那只在花丛边飞舞的蝴蝶。

• mesh

  Mesh describes the woven material itself — crossed threads or wires forming small, even holes — used as a fabric or screen, such as wire mesh or mesh fabric, without the idea of a tool for catching something.

  mesh指的是材料本身——由交叉的线或金属丝织成、带有细小均匀孔洞的网状物，常用作纱网或网眼织物，比如金属网、网眼布料，并不带有“捕捉工具”的意味。

  Her running shoes are made from breathable mesh fabric that keeps your feet cool.

  她的跑鞋是用透气的网眼面料做的，能让脚保持凉爽。

Both words can mean net-like material. Net names a finished object, often with a frame, used to catch, hold, or block things, like a fishing net. Mesh describes the woven material itself, crossed threads or wires with small, even holes, like wire mesh.

这两个词都能表示“网状”“网眼”材料，容易被混用：net更强调这是一件用来捕捉、盛装或阻挡东西的成型物品（比如渔网、球门网），而mesh更强调材料本身由细线或金属丝交叉编织而成、孔洞均匀，常用来指纱网或网眼布料，并不强调“捕捉工具”这一属性。

Compared meaning: money earned from work or business (noun).

比较义项：利润、收益（名词）。

• profit

  The everyday, general word for money a business gains above its costs. Usually takes an article, 'a profit' or 'the profit'. The fixed phrase 'make a profit' is very common and neutral in tone.

  最常用、最普通的词，指企业扣除成本后赚到的钱。前面通常加冠词，如 a profit 或 the profit；常见固定搭配 make a profit，语气中性。

  The bakery finally started making a profit after cutting its costs.

  面包店削减成本后，终于开始赚取利润了。

• net 本词

  A more formal, finance-register word for the final amount left after all costs and taxes are subtracted, contrasted with 'gross'. Often stands alone as a noun in accounting contexts, rare in everyday speech.

  语域更正式，属财务用语，指扣除所有成本和税款后剩下的最终金额，常与 gross（毛额）相对。单独作名词多见于会计语境，日常口语中较少使用。

  The report showed a net of just three percent after taxes.

  报告显示，扣税后净利润仅为百分之三。

• earnings

  Refers broadly to money made from work or business over a period. In this sense it is usually plural and used without an article, common for salaries or company financial reports.

  泛指工作或经营在一段时间内所赚的钱，此义项常用复数形式且不加冠词；常用于描述工资收入或公司的财务报告。

  Company earnings dropped sharply after the factory closed down.

  工厂关闭后，公司的收入大幅下降。

Profit, net, and earnings all mean money made from work or business. Profit is the everyday word for earnings above costs. Net is the formal term for the amount left after costs and taxes. Earnings is broader, usually plural, for income from work.

这三个词都表示因经营或工作而获得的钱，但用法和搭配不同：profit 最常用；earnings 常指工资或公司整体收入；net 则强调扣除成本后的最终数额，多用于财务语境。这里不比较 net 的「渔网」义，也不比较 profit 用作动词「获利」的用法。
