Language is an important aspect in our day to day life because it enables us to communicate. The effective communication is made possible with the help of language. Language employs a combination of words to communicate ideas in a meaningful way. By changing the word order in a sentence, you can change its meaning, and even make it meaningless. Language is created by people. It does not exist in isolation or outside the minds of people. It is created by people as they need it. Humans attach meaning to words as they need to and modify these meanings according to changing needs.
Human language has the properties of productivity, recursively, and displacement, and relies entirely on social convention and learning. Its complex structure affords a much wider range of expressions than any known system of animal communication. Language is thought to have originated when early hominines started gradually changing their primate communication systems, acquiring the ability to form a theory of other minds and a shared intentionality. This development is sometimes thought to have coincided with an increase in brain volume, and many linguists see the structures of language as having evolved to serve specific communicative and social functions. Language is processed in many different locations in the human brain, but especially in Broca's and Wernicke's areas. .
Humans acquire language through social interaction in early childhood, and children generally speak fluently when they are approximately three years old. The use of language is deeply entrenched in human culture. Therefore, in addition to its strictly communicative uses, language also has many social and cultural uses, such as signifying group identity, social stratification, as well as social grooming and entertainment.
Languages evolve and diversify over time, and the history of their evolution can be reconstructed by comparing modern languages to determine which traits their ancestral languages must have had in order for the later developmental stages to occur.
