易混淆词

predecessor
EN: 'Predecessor' refers specifically to a person or thing that previously held a position or role; 'precursor' is broader, referring to anything that comes before and signals the approach of something else.
zh: 'Predecessor' 特指曾经担任过某个职位或角色的人或事物；'precursor' 含义更广，指任何在之前出现并预示某事即将发生的事物。
harbinger
EN: 'Harbinger' emphasizes being a sign or omen of something to come; 'precursor' emphasizes being a direct forerunner or early stage of something.
zh: 'Harbinger' 强调是未来某事的征兆或预兆；'precursor' 强调是某事的直接先驱或早期阶段。

拼写提示

EN: Remember 'precursor' has only one 'r' before the final 'sor' ending (not 'precursour' or 'precursur'). It is often misspelled as 'precursory' when the noun is intended.
zh: 请记住 'precursor' 在结尾的 'sor' 之前只有一个 'r'（不是 'precursour' 或 'precursur'）。当意图使用名词时，它常被误拼为 'precursory'。
