• Let's take a look at some negative prefixes.
  - negative prefix 帶有否定含意的字首
• The most common negative prefixes in English are: in-, un-, non- and anti-
• Q: How do you know which one to use?
  A: Well, there are some general guideline and some history.

1. Simply speaking "in-" is usually used when the English word is come from Latin. Like inaccurate or intolerant.
   來自拉丁文的英文單字，使用"in-"字首
2. "un-" usually proceed most other adjectives, including the Latin words that ending in "ed", like undiluted.
   幾乎所有否定adj.都是用"un-"作為字首，例如：unhappy, unkind
3. When using "un-" before a verb, it just means to undo something.
   You do something and if you want to reverse it, you undo it.
   Also, sometimes if you use "in-" versus "un-", you change the meaning.
   ex: inhuman means ... 無情的，冷酷的, unhuman means nonhaving human qualities or have more human qualities, like be superman. (非人類的超人)
   un- 也可比用在動詞，表示解除的意思，但需特別注意的是，同一字可用不同的否定字首表示不同意義
4. "non-" is the ... of the negative prefixes, and can come before almost any word, however, it often contrast with "in-" or "un-", because it does not show the opposite end of the skill, but something that is not majored. 使用最廣泛的否定字首
   ex:
   ┌nonscientific is concerned with the fill other than science. 非科學的
   └unscientific means something is not done using scientific preciples. 沒有科學根據的
5. "anti-": which just means "against", like antiwar means against the war. 反對~
