Week 1: Introduction to Historical Linguistics. The Comparative Method. The Parametric Comparison Method (PCM). Case Study: The Indo-European Language Family. Language trees and language contact. Case Study: The Balkan Sprachbund.
Week 2: Parameter Setting for PCM. Case study: Analysing Syntactic Parameters in Participants’ Languages. Data Visualisation: Gradient Maps of Principal Components and Their Historical Implications. Exploring Migrations and Cultural Contact through Linguistic Evidence. Clustering Techniques for Phylogenetic Tree Generation. Advanced Tools: Using Large Language Models (LLMs) for Parameter Evidence Collection.
Week 1 covers the basics of the classical (lexical-etymological) comparative method for phylogenetic reconstruction and a full introduction to the innovative syntactic-parametric method. The theory of parameters from the perspective of language typology and of language acquisition will be introduced. Then it will be shown how to apply current syntactic wisdom and models to define the grammar of a new language (set its parameters) starting from either speakers’ knowledge or portions of text. The place of historical linguistics among cognitive neurosciences will be discussed.
Week 2 focuses on applying the knowledge acquired in Week 1 to collecting data on syntactic parameters and its use in historical linguistics. Participants will systematically analyze the syntactic parameters of their chosen language by responding to a predefined set of questions for each parameter and documenting example sentences that serve as evidence. The collected data will be integrated with existing datasets to generate gradient maps of principal components in the tradition of Cavalli-Sforza’s work in genetic classification of populations, facilitating discussions on their potential relevance as evidence for historical migrations and cultural contact. Additionally, participants will acquire hands-on experience with clustering techniques derived from bioinformatics to construct phylogenetic trees based on the compiled data. The week will conclude with an exercise in employing large language models (LLMs), such as ChatGPT, to assist in the identification and documentation of syntactic parameters of a given language.
