precise

Compared meaning: correct or exact (adjective).

比较义项：正确的、精确的（形容词）。

• right

  The everyday, informal word for something correct; used for answers, directions, choices and simple facts. It does not imply careful measurement, so it sounds too casual for scientific or technical accuracy.

  口语化、最笼统的“正确”，常用于回答、方向、选择和简单事实；不强调仔细测量，用在科学或技术上的精确度时会显得过于随意。

  Is that the right way to spell 'necessary'?

  这是拼写“necessary”这个词正确的方式吗？

• precise 本词

  Stresses exactness down to fine detail, especially with numbers, measurements or instructions; something can be accurate without being precise. Common in technical, scientific or mathematical contexts, less so in everyday chat.

  强调精确到具体细节，常用于数字、测量或说明；某物可以“准确”却不“精确”。多用于技术、科学或数学语境，日常闲聊中较少使用。

  The instructions gave precise measurements, down to the exact gram.

  说明书给出了精确的测量数据，精确到克。

• correct

  The neutral, fairly formal word for free of mistakes; typical in grammar, schoolwork, forms and factual checking. It focuses on matching a fixed standard rather than describing measurement or detail.

  中性、较正式的“没有错误”，常用于语法、作业、表格和事实核查；强调符合既定标准，而不是描述测量或细节。

  Please make sure every answer on the form is correct before you submit it.

  请确保表格上的每一个答案在提交前都是正确的。

• accurate

  Describes information, measurements, predictions or instruments that closely match reality; stresses reliability and truthfulness, often used for data, forecasts and reports rather than simple everyday facts.

  形容与事实高度相符的信息、测量、预测或仪器，强调可靠性和真实性，常用于数据、预报和报告，而非日常简单事实。

  The weather forecast turned out to be accurate, predicting the storm exactly.

  天气预报后来证明是准确的，准确预测了那场风暴。

Right, precise, correct, and accurate all mean 'correct', but differ in tone. Right is the casual, general word. Correct is more formal, stressing freedom from mistakes. Accurate stresses matching the facts. Precise stresses exactness in detail. Right's senses and correct's verb use are not compared.

这四个词在“正确”这一意义上很接近，但语气和使用场合不同：right最口语、最笼统，correct更正式、强调没有错误，accurate强调数据或预测等与事实相符，precise则强调精确到细节。这里不比较right的其他意义（如“右边”“权利”），也不比较correct用作动词的“纠正”这个意义。
