One thing that makes humans unique is our ability to talk. We, humans, communicate in various ways that are far more complex than other animals. 

Language is a mode of communication. It consists of sounds and written symbols that we use for talking or writing and are an integral part of humans. All living species have their way of communication. But only humans have mastery over cognitive language communication because part of our brain – the cerebral cortex – is dedicated to language. Without language, nothing alive would exist. It would be a lifeless world. We use language to express ourselves and share our feelings. Most of this language-related brain activity is likely occurring in the left side of our brain. 

Languages we speak reflect our thoughts and helps communicate our opinion more effectively. It also helps to showcase to others how we see the world, how we think, and how we live our lives. Language is the foundation of any effective communication process, and that it’s hard to imagine life without it.  

Language is multidimensional, revealing and powerful. It serves as an insight into our thought process. Language can be well organised into five systems of rules – phonology, morphology, syntax, semantics and pragmatics. The morpheme is the most minimal unit of meaning in a language. It is these units that work together to create sense in our languages. The sound system of a language is called Phonology. It includes the sounds used in that language and combining sounds. The grammar rules in determining word order, word placement, and word combination are echoed in the language rule of syntax. Semantics is the study of the meaning and interpretation of language, e.g. words, phrases, sentences, etc. Pragmatics go beyond the basics of communication and help us develop our language to fit specific social contexts in our culture.¹ 

Further, research shows that learning more languages and effectively has an impact on the brain. It supports boosting the size and activity of specific brain areas in addition to our separate “language centres.” 

Studies suggest that the more languages we learn, especially during childhood, the easier our brains to retain new information. 

Thus, adding new language skillsets at an early age is vital and long-lasting for the comprehensive growth of children. The effect and value of language are such that we as an individual should try to be multilingual.
