Language is the medium of communication between humans. There are thousands of languages which are spoken around the world. When one has to talk about languages, there can be sign language, written language, and spoken language. Even computer programs are written in different 'computer languages'. Animals also have their own languages, which they use to communicate with each another. In simple words, a language is a system of signs used for encoding and decoding information being relayed out. Languages came into existence when Homo sapiens started coordinating with one another. Eventually, the use of language became an important part of human culture. It was not only used to communicate and share information, but it also had many social and cultural uses. It came to be used for identifying a group, social grooming, entertainment, etc., among other things. As time passed, many languages evolved and diversified, when people started traveling from one part of the world to another. When one has to look at the list of languages spoken in the world today, most of the languages belong to the same family. This language family is known as the 'Indo-European' family. The languages that are a part of this family are languages like English, Spanish, Hindi, etc. Another language family which also has a number of people speaking them is the 'Sino-Tibetan' language family. The languages that are a part of this family are Chinese, Cantonese, etc. The next family is the 'Semitic' languages family, of which, a famous language is Arabic. The 'Bantu' language family comprises the different languages spoken in Africa, like Swahili, etc. When we have to make a list of the languages spoken in the world, we will have to make use of some criteria, with which we will group the languages.
