"无误"是汉语成语，指的是事物或表达的意思准确、确切。在日常生活中，“无误”常用来形容对某人的认识和评价十分恰当。 在英语中，“无误”也有其用法。例如： 1. It was a correct diagnosis, the results of which were unambiguously no more than I could have expected. (It had a correct diagnosis and the result was unambiguous.) 2. The patient was given an irrefutable medical testimony in his case. (He received a reliable medical evidence in his case.)
