Constructing a Phonetic Map and Morphological Finite Automata for Linguistic Analysis across Languages

Core Concepts
By leveraging Pānini's system of sounds and finite state machines, this paper proposes a formal approach to analyze and represent word relationships across languages, enabling a more comprehensive understanding of linguistic evolution and connections.
The paper introduces the concept of m-alphabet and m-language to analyze words across languages. The m-alphabet represents the core set of sounds used to construct a word, while the m-language represents a group of related words that are phonetically, semantically, grammatically, and ontologically connected. The authors first provide an overview of linguistics, highlighting the contributions of Pānini and the evolution of comparative linguistics. They then analyze words from Sanskrit, European, and Dravidian languages using Pānini's system of sounds, identifying sound shifts, replacements, and losses that occur as words transform across languages. The authors propose the use of Morphological Finite Automata (MFA) to formally represent the m-languages. Each m-language has a core m-alphabet and an extended m-alphabet, allowing for the systematic analysis of word relationships and the identification of candidate words that may belong to the same word group. The paper also discusses the limitations of the mainstream view on the relationship between Sanskrit and other Indo-European languages, proposing an "Ecosystem Model for Linguistic Development" with Sanskrit at the core, in contrast to the widely accepted family tree model.
"Sanskrit, being the most comprehensive and ancient language, has served as the donor language of words that represent abstract concepts as well as mundane reality across Indian languages." "Dravidian languages have a significant number of Tadbhava words that are derived from Sanskrit, contrary to the widely held belief that they are disjoint from Aryan languages." "The transformation of Sanskrit words in European languages can be considered as manifestations of the same phenomena that happened as the words got carried over, similar to the transformations observed in Indian languages."
"Pānini's method of analyzing words consists of observing the repeated occurrences of letters or groups of letters in different words, observing the repetition of the same meaning in different words, mapping repeating sounds with repeating meanings, and assigning meaning to the components of a word." "According to Swaminath Aiyar, a large number of Dravidian words, in particular in Tamil that appear to have no affinity with Sanskrit are Tadbhava words from Sanskrit. As Tamil has a highly constrained Alphabet, they went through a lot more transformation and corruption compared to North Indian Vernaculars and appear unrelated."

Deeper Inquiries

How can the proposed approach of m-alphabet and m-language be extended to analyze the evolution of words across a broader range of languages, including non-Indo-European and non-Dravidian language families

The proposed approach of m-alphabet and m-language can be extended to analyze the evolution of words across a broader range of languages by incorporating a comparative linguistics framework. This extension would involve creating a comprehensive database of words from various language families, including non-Indo-European and non-Dravidian languages. By identifying common phonetic and semantic patterns across languages, researchers can establish m-languages that group words with similar evolutionary origins. To analyze the evolution of words in diverse language families, researchers can utilize historical linguistic data, etymological dictionaries, and language corpora. By tracing the phonetic shifts, semantic changes, and morphological adaptations of words across different language families, it becomes possible to identify cognates, loanwords, and shared linguistic features. The m-alphabet can be expanded to include phonemes and sounds specific to non-Indo-European and non-Dravidian languages, allowing for a more inclusive analysis of word evolution. Furthermore, the m-language approach can be applied to study language contact situations, language borrowing, and the impact of cultural interactions on vocabulary evolution. By examining how words have been borrowed, adapted, and integrated into different language systems, researchers can gain insights into the interconnectedness of languages and the processes of lexical diffusion and language change.

What are the potential limitations or challenges in applying the finite state machine-based approach to capture the nuances and complexities of natural language evolution, especially in cases of extensive borrowing, language contact, and language change over time

Applying the finite state machine-based approach to capture the nuances and complexities of natural language evolution poses several potential limitations and challenges. Some of these include: Complexity of Language Evolution: Natural languages evolve over time through a combination of internal changes, external influences, and socio-cultural factors. Capturing the intricate processes of language evolution, including sound shifts, semantic drift, and grammatical innovations, using finite state machines may oversimplify the dynamic nature of linguistic change. Variability in Language Contact: Languages often come into contact with multiple linguistic systems, leading to complex patterns of borrowing, code-switching, and language convergence. Finite state machines may struggle to account for the diverse ways in which languages interact and influence each other, especially in multilingual and multicultural contexts. Historical Linguistic Data: Access to comprehensive historical linguistic data for a wide range of languages can be limited, making it challenging to construct robust m-languages and analyze word evolution accurately. Incomplete or biased datasets may lead to skewed interpretations of language relationships and evolution. Semantic Ambiguity: Words in different languages can have multiple meanings and semantic nuances, making it challenging to establish clear one-to-one correspondences between words in different languages. Finite state machines may not adequately capture the subtle semantic shifts that occur during the evolution of words. Computational Complexity: Analyzing the evolution of words across diverse language families using finite state machines may require significant computational resources and processing power. Handling large datasets, complex linguistic patterns, and cross-linguistic comparisons can be computationally intensive and time-consuming.

Given the historical and cultural significance of Sanskrit, how can the "Ecosystem Model for Linguistic Development" proposed in the paper be further developed and validated to provide a more comprehensive understanding of the relationships between various language families and their evolution

The "Ecosystem Model for Linguistic Development" proposed in the paper, with Sanskrit at the core, can be further developed and validated to provide a more comprehensive understanding of the relationships between various language families and their evolution by: Cross-Linguistic Comparison: Conducting in-depth comparative studies across a wide range of language families to identify shared linguistic features, cognates, and language contact phenomena. By expanding the analysis beyond Indo-European and Dravidian languages, researchers can uncover deeper connections and historical relationships between diverse language groups. Historical Linguistic Reconstruction: Utilizing historical linguistic methods to reconstruct proto-languages, trace language families back to their common origins, and analyze the evolution of vocabulary and grammar over time. By integrating historical linguistic data from multiple language families, the model can provide a more holistic view of linguistic development. Semantic Networks: Developing semantic networks that map the meanings and associations of words across different languages, highlighting semantic universals, cultural concepts, and shared cognitive structures. By exploring the semantic relationships between words in various languages, the model can reveal underlying patterns of conceptual organization and linguistic thought. Interdisciplinary Collaboration: Collaborating with experts in fields such as anthropology, archaeology, genetics, and cognitive science to incorporate multidisciplinary perspectives on language evolution and human migration. By integrating insights from diverse disciplines, the model can offer a more nuanced understanding of the complex interplay between language, culture, and human history. Validation and Verification: Validating the model through empirical studies, linguistic fieldwork, and computational analyses to ensure its accuracy, reliability, and applicability to diverse linguistic contexts. By testing the model against real-world language data and historical evidence, researchers can refine and enhance its predictive power and explanatory capacity.
