Pain, nuisance, and annoyance can all mean something annoying. Pain is informal, often for a person who irritates you. Nuisance is neutral, for a person or thing that repeatedly causes trouble. Annoyance is formal and abstract, usually the feeling itself, not used for a person.

这三个词都可以表示“讨厌的人或事”，但语气和用法不同：pain 非正式且常直接用于人，nuisance 中性，常指反复惹麻烦的人、动物或事物，annoyance 更正式、更抽象，多指令人恼怒的事或感觉本身，一般不用来形容人。这里不比较 pain 的“疼痛”义。
