It Sarcasm is a strong form of irony. It attacks in a taunting and bitter manner, and its aim is to disparage, ridicule and wound the feelings of the subject attacked. For example, laws are like cobwebs, which may catch small flies, but let wasps break through.

It is a figure of speech consisting of a statement or proposition which on the face of it seems self-contradictory, absurd or contrary to established fact or practice, but which on further thinking and study may prove to be true, well-founded, and even to contain a succinct point. For example more haste, less speed.

It is a compressed paradox, formed by the conjoining(结合) of two contrasting, contradictory or incongruous(不协调) terms as in bitter-sweet memories, orderly chaos(混乱) and proud humility(侮辱).

It is the opposite of Climax. It involves stating one's thoughts in a descending order of significance or intensity, from strong to weak, from weighty to light or frivolous. For instance, But thousands die, without or this or that, die, and endow(赋予) a college, or a cat.

It is a figure of speech where an epithet (an adjective or descriptive phrase) is transferred from the noun it should rightly modify(修饰) to another to which it does not really apply or belong. For instance, I spent sleepless nights on my project.

It has to do with the sound rather than the sense of words for effect. It is a device that repeats the same sound at frequent intervals(间隔) and since the sound repeated is usually the initial consonant sound, it is also called "front rhyme". For instance, the fair breeze blew, the white foam flew, the furrow followed free.

It is a device that uses words which imitate the sounds made by an object (animate or inanimate), or which are associated with or suggestive(提示的) of some action or movement.
