What is language? Language is the fundamental and indispensable thing in human life. Language is a bridge of communication between people, countries or the world. The language is also linked to the culture of the country. There are many types of language in the world that can be used to communicate. Language can be used to express oneself or understand other people. Language is processed in many different places in the human brain, but especially in Broca's and Wernicke's areas. Children generally speak fluently when they are around three years old. Language use is deeply rooted in human culture. (APA 6, p. 205; Electronic References, p. 19) When you read, listen to speech, sign, or speak, a network of thousands of neurons is activated in our brains. This provides an overview of the brain regions thought to participate in various stages of language processing. When we say “language,” people's first reaction is spoken language. In reality, language includes written language, body language and lip language. Lip speaking is another action that involves looking at your lips when speaking to other people. It's kind of a difficult skill and requires a lot of practice, no one can teach people how to use lip speech. Hearing-impaired people may use dactylophasia or lip-speak to communicate with others. Sign language and eye contact are both included in body language. Body language normally uses the torso, arms, hands, fingers, feet, and legs (e.g., power poses, leaning back in a chair or hunching over, keeping hands in pockets, not maintaining contact visual). We always use body language in our life, such as shaking people's hands when meeting or greeting each other or shaking when people are shaking. Body language is also useful in psychology; it's the first... middle of the paper... a modern vocabulary for English. Language is the most important communication tool for people to communicate in symbolic expression. People transmit culture through the linguistic achievements of human civilization. Language is an important characteristic of the nation. In general, each nation has its own language. Chinese, English, French, Russian, Spanish and Arabic are the main languages ​​of the world and are also the working language of the United Nations. Chinese is the most popular language in the world; English is the most used language in the world. According to the German publication “Linguistics and Language Communication Tools Handbook,” the world has now identified 5,651 types of languages. In these languages, approximately more than 1400 types have not been recognized as separate languages ​​or are in decline and fall. Surprising.
