In countries like India, the term used to mark the difference between local languages and everyday use of English is "Vernacular." The British used this term during their colonial rule to differentiate between the local languages or dialects and what they considered as the standard language, which was English.

Vernacular refers to the native language or dialect spoken by people in a particular region or community. It is the language that is commonly used in everyday conversations, informal settings, and local contexts. The term vernacular is often associated with the non-standard or non-prestigious language spoken by the common people.

- The British colonialists used the term vernacular to distinguish the local languages from the English language, which they considered as the language of power, education, and administration.
- The vernacular languages in India vary greatly across different regions and communities. For example, Hindi, Tamil, Bengali, Punjabi, and Marathi are some of the major vernacular languages spoken in different parts of India.
- These vernacular languages have their own distinct grammar, vocabulary, pronunciation, and writing systems. They are deeply rooted in the culture and history of the region and are often used as a means of expressing local identities and traditions.
- In contrast, English was introduced by the British and became associated with power, education, and upward mobility. It was primarily used in formal settings, government institutions, education, and business.
- The term vernacular is used to highlight the difference between the local languages and the English language in terms of their usage, social status, and cultural significance.
- Today, English has gained a significant status in India and is widely spoken and understood across the country. However, the vernacular languages continue to play a crucial role in people's everyday lives, literature, media, and cultural expressions.

In conclusion, the term vernacular is used to refer to the local languages or dialects spoken in a particular region or community, distinguishing them from the standard language, which in this case is English. The British colonialists used this term to mark the difference between the local languages and English during their rule in countries like India.
