'Colloquial' is a language spoken normally every day which is informal in nature. 'Indigent' is a poor needy person, So from the above words, the word 'Indigent' does not talk about any local or regional thing like all the others. Hence it is not a synonym for the word vernacular.
Introduction
The word vernacular means the way people use language in a specific country or region. For instance, while English is a common language in places like the US, the UK, New Zealand, and Australia, the way that people use English is vernacular—it varies from country to country. Vernacular can also be specific to a culture, such as African American Vernacular English (AAVE).
Synonyms
Colloquialism: Informal phrases used in everyday conversation.
It’s a synonym because: Both colloquialism and vernacular include phrases that are recognized in specific regions and are used in casual conversation.
Dialect: A form of a language used in a specific region or by a particular social group.
It’s a synonym because: Both dialect and vernacular deal with regional-specific language use as well as language use by specific social groups.
Slang: Informal words or phrases that are often used by a specific group of people.
It’s a synonym because: Both slang and vernacular are types of language used by a select group, and both can break established grammar rules.
Antonyms
Formal: Language used in accordance with social rules of etiquette, often in official contexts.
It’s an antonym because: Vernacular is defined as the informal language, like slang, that is used in a region or by a culture, while formal language excludes such language.
Literary: Stylistic language used in works of literature.
It’s an antonym because: Literary language is not typically used in everyday contexts, while vernacular language is used that way.
Uncommon: Something that is rare. In the context of language, it would include words or phrases that few, if any, people use regularly.
It’s an antonym because: Vernacular language is common among a group of people and can be heard in everyday life, while uncommon language is not.
Conclusion
We don't compose essays for our English class the same way we communicate to our friends. The term "vernacular" describes our straightforward, common language. It's the language we use when we text our closest friend or when we speak informally to our siblings. Even slang and obscenities are part of the vernacular. So it stands to reason that the speech of a group of Princeton engineering professors conversing informally over lunch would sound very different from that of a bunch of young girls at a sleepover.
