Language is an integral part of our society; it uses a series of systems to convey meaning, thus setting up a discourse community. The surrounding environment plays a major role in our language as a social practice. Language is a form of communication involving an organized system of symbols whether written, spoken or pictures. Language is purposeful, built on shared conventions, shaped by the context and constitutes texts of various sorts and " language is the source of human life and power" (Fromkin).
Language is used to achieve a variety of social purposes: for example, we use it to entertain, to explain how some thing works, to provide information. We also use language to make sense of the world, to express ideas on a range of topics and to interact with various audiences. People need to be able to communicate confidently and appropriately with people of all walks of life: with those who are older or younger, with those in positions of power, with peers and family, with small and large groups. .
Language plays a very important role in my daily life. It allows me to communicate and exchange meaning with others. It is necessity to help find meaning of everyday experiences and to help me to understand the complexities of the world. Language isn't just words; it includes pictures, written and oral language, sign language, gestures and body language, signs and any other practice that conveys meaning. .
Formal English is, for the most part, a written language. In general, it is confined to the realm of the serious: textbooks, academic or technical works, and most essays. It is appropriate to write formally in a letter of application for a job. Formal language tends to be impersonal and precise, and uses long, carefully constructed sentences; the formal writer should avoid contractions and abbreviations, and will use a more specialized and complex vocabulary than that used in everyday speech.
