There are three elements that constitute the content of a metaphor:

The first is the object of thought, that is, the original intention;

The second is other things, the metaphor;

The third is the similarity between two things (***similarities and similarities).

The role of metaphor:

1. Use metaphors to describe and render the characteristics of something. It can make things vivid, concrete and perceptible, thereby stimulating readers' association and imagination.

2. When explaining or reasoning, it is not called "metaphor" but "analogy". Use easy-to-see things to describe profound principles, turn abstraction into concreteness, and simplify the complex to help people understand deeply. And make the language vivid and full of literary talent.

The sounds that small raindrops can make: tick-tock, patter.

Didi-tak-ta, which means onomatopoeia, is a vernacular vocabulary in modern Chinese. In ancient times, the word was relatively rare and it was a frequently used Chinese vocabulary. It is more common in general situations. There are detailed records about this word in "Shuowen Jiezi".

Pitter patter is an onomatopoeia, describing the slight sound of wind, rain, falling leaves, etc. Generally refers to the sound of light rain falling.

Although onomatopoeia also imitates natural sounds, it is highly subjective. There are infinite sounds in nature. Through the interpretation of our ears and brains, the subjective perception of sound, and then simulated by the phoneme system of our own language, such simulations are often distorted.

Therefore, it is different from the sound imitation of ventriloquism.

Onomatopoeia is mostly used to describe and describe, so some people classify it as an adjective. Some people also classify the sounds caused by subjective feelings and emotions into onomatopoeia.
