In Nyaya philosophy, language is primarily seen as a tool for conveying information and knowledge. It is believed that words have inherent meanings that correspond to real objects and concepts, and that language enables us to communicate these meanings to others.

Mimamsa philosophy places great importance on the performative aspect of language, particularly in the context of rituals and religious ceremonies. It is believed that certain words and phrases, when uttered in the proper context, can have real-world effects, such as purifying the speaker or invoking divine powers.

Advaita Vedanta posits that Brahman, the ultimate reality, is ineffable and beyond the reach of language. However, language can be used to point towards Brahman or to express its qualities. In this sense, language is seen as a manifestation of Brahman, albeit an imperfect and limited one.

Bhartrihari, a renowned philosopher of the 7th century CE, proposed the theory of 'sphota', which suggests that language is not merely a collection of sounds or symbols, but rather a unified and meaningful entity. He argued that language shapes our perception of reality by providing us with categories and concepts through which we interpret the world.

Buddhist philosophy emphasizes the concept of emptiness, which refers to the inherent lack of inherent existence of all phenomena. Language, with its tendency to create fixed and separate entities, is seen as an obstacle to realizing this emptiness. The ultimate goal is to transcend language and directly experience the non-dual nature of reality.

Dharmakirti, a prominent Buddhist philosopher of the 7th century CE, developed the theory of 'apoha', which posits that the primary function of language is to negate or exclude certain qualities from an object. According to this theory, language operates by identifying what an object is not, rather than what it is.

The Sapir-Whorf hypothesis, also known as the linguistic relativity hypothesis, proposes that the structure of a language influences the way its speakers perceive and conceptualize the world. In other words, the language we speak shapes our understanding of reality.

Abhinavagupta, a renowned Kashmiri Shaivite philosopher of the 10th-11th centuries CE, proposed the theory of 'abhivyakti', or expression. He argued that language is not merely a tool for describing reality, but rather a creative act that brings new realities into existence. According to Abhinavagupta, poetic language, in particular, has the power to transform the reader's consciousness and reveal hidden dimensions of reality.

Denotation refers to the literal, objective meaning of a word, while connotation refers to the subjective, emotional, or implied meaning. For example, the word 'home' may literally denote a physical structure, but it may also connote feelings of comfort, security, and belonging.

Jayanta Bhatta, a renowned Nyaya philosopher of the 9th century CE, proposed the theory of 'anvayavyatireka', or concomitance and absence. He argued that the meaning of a word is determined by its consistent association with a particular object or concept. According to Bhatta, language is a mirror of the mind, reflecting the speaker's inner thoughts and feelings.

Performative utterances are those that, by being uttered, bring about a change in the world. Examples include promises, declarations, and requests. Constative utterances, on the other hand, are those that simply describe the world and do not change it. Examples include statements of fact and reports.

Kumarila Bhatta, a prominent Mimamsa philosopher of the 7th century CE, argued that language is a conventional system of symbols that has no inherent connection to reality. He believed that words are merely arbitrary labels that we assign to objects and concepts. According to Bhatta, the meaning of a word is determined by social convention rather than by any essential or natural relationship between the word and the thing it signifies.

Analytic statements are those that are true by definition or by virtue of the meanings of the terms they contain. For example, the statement 'All bachelors are unmarried' is analytic because the term 'bachelor' already implies the concept of being unmarried. Synthetic statements, on the other hand, are those that are true based on experience or empirical evidence. For example, the statement 'The sky is blue' is synthetic because its truth depends on our observation of the sky.

Sri Aurobindo, a renowned Indian philosopher and yogi of the 20th century, argued that language is a tool for liberation. He believed that language has the power to transform consciousness and reveal the true nature of reality. According to Aurobindo, the ultimate goal of language is to transcend the limitations of the mind and experience the divine consciousness.
