如果名词单数词尾为-f或-fe（读作／f／），则其复数一律变为-ves （读作／vz／），即将-f或-fe变成-v，再加-es而成，如 housewife ---- housewives。
英语中有一些名词的复数形式是不规则的，如man与woman其复数形式分别为men与women。此外还可用man，woman等来区别阳性与阴性：以-man结尾的一些复合名词指男性，如milkman ---- milkmen，policeman ---- policemen；一些以-woman结尾的名词指女性，如postwoman ---- postwomen，policewoman ---- policewomen。
200 ---- two hundred
1,000 ---- a（或 one） thousand
