先看一下英文解釋

irony : 1) the amusing or strange aspect of a situation that is very different from what you expect

2) the use of words that say the opposite of what you really mean,often as a joke and with a tone of voice that shows this

satire : a way of criticizing a person ,an idea or an institution in which you use humour to show their faults or weaknesses

sarcasm : a way of using words that are the opposite of what you mean in order to be unpleasant to sb or to make fun of them

可見 irony 和 sarcasm 都有反語的意思 而 sarcasm通常指對人進行

挖苦嘲諷，irony可以指其他事物。

satire和上面兩個有區別，是指透過幽默對人，想法或機構的諷刺和取笑

比如諷刺社會的陰暗面等。
