added to the beginning of a word to form its opposite or to show that a person or thing does not have the expected quality — for example, 'non-smoker' means a person who does not smoke, 'non-fiction' is writing about real events, and 'non-profit' describes an organisation that does not aim to make money

例句

The hotel has both smoking and non-smoking rooms for guests.

這家飯店同時提供吸菸房和禁菸房給客人選擇。

non- + [gerund adjective]: non-smoking

Christopher ordered a non-alcoholic drink at the party.

Christopher 在派對上點了一杯無酒精飲料。

    used with Latin-derived adjectives (inactive, invisible); less productive in modern English

  • dis-

    reverses or removes (disagree, disapprove), whereas non- simply negates without implying a prior state

    suffix with positive connotation (sugar-free, smoke-free); non- is neutral

non- + [noun]

用法筆記

The hyphen after non- is common but not always required; many established compounds are written as a single word (e.g. nonstop, nonfiction). Check a dictionary when unsure, especially for formal writing. This prefix attaches freely to almost any adjective or noun, but note that some words have developed specialised compounds (non-profit, non-stick) where the meaning goes beyond simple negation.

常見錯誤

❌This is a non sense answer.
✅This is a non-sense answer.
💡'non-sense' means 'not making sense'; 'nonsense' is the standard spelling for the noun meaning 'ridiculous talk'.
❌She is a non-smooker.
✅She is a non-smoker.
💡The base word must be spelled correctly; the prefix non- attaches to the unchanged word.
❌This is a non-profitable organisation.
✅This is a non-profit organisation.
💡'non-profit' is the standard compound; 'non-profitable' is rare and may confuse readers.

用法筆記

Distinguish from sense 1: sense 1 simply negates a category (non-smoker = a person who does not smoke), while sense 2 describes something that deviates from an established norm (non-standard = not conforming to the standard, suggesting a contrast with what is normal or expected). The object is typically an abstract concept such as a method, approach, spelling, or belief.
