Reconstructing language history and prehistory in the context of the Indo-European language family.

Almost all languages of Europe and of a large part of western Asia belong to a single language family, which is called Indo-European, and which includes modern languages like English, Dutch, Russian, Farsi, but also ancient ones like Ancient Greek, Latin, Hittite and Sanskrit.

Indo-European is the name of the language family to which English belongs, along with many sub-families such as Germanic languages and Romance languages. In this course, you will delve into the structure and origins of these branches, the oldest languages belonging to the language family, linguistic…

Set up in 1991, this unique project aims to identify and describe the common lexical heritage of the most important Indo-European languages and language branches. The project has thus far resulted in twelve volumes published as The Leiden Indo-European Etymological Dictionary Series (Brill, Leiden).

The study of language in change.

Nowadays, most Europeans speak a language belonging to the Indo-European language family. However, very different languages were spoken on our continent before the arrival of the Indo-Europeans.

This dissertation focuses on the systematic vowel alternations displayed by the Proto-Germanic n-stems. The fact is, that many of these nouns now appear to have preserved the ablaut system of the Indo-European proto-language spoken some five millennia ago. In this respect, the n-stems are truly comparable…

This dissertation provides an up to date description of the Indo European lexical stock of Armenian (ca. 500 entries) with systematic inclusion of unused data that are found in Armenian dialects.

This dissertation attempts to describe the linguistic history of Hittite on the basis of a systematic etymological treatment of its entire inherited lexicon, precisely analyzing the phonological and morphological developments.

Language plays a central role in human life. We use it every day to communicate, learn and share ideas. But how do children acquire their first language? Why do languages differ from one another? And how do adults learn new ones? Linguistics is the scientific study of language and seeks to answer these…

Ancient Greek was spoken in a large number of different dialects. Although we do not find direct evidence for syllabic liquids in any of our sources, comparative evidence shows that these sounds must have been present in Proto-Greek, and that they were retained until comparatively recently in the prehistory…

Niya Prakrit, a dialect of Central Asian Gāndhārī, served as the administrative language of the former Shanshan kingdom (3rd–4th century CE; Xinjiang Uyghur Autonomous Region, Northwest China).

The Latin language is a descendant of the widespread Indo-European family of languages. Recent ancient genetic studies have helped shed light on the likelihood that the Indo-European languages spread into a Europe that had already been populated by farmers for thousands of years.

On the 23rd of March, Alessandro del Tomba successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Alessandro on this achievement!

Bringing together a globally representative team of scholars, this Handbook provides a comprehensive overview of comparative syntax, the study of universal and variable properties of the structure of building blocks in natural language.

This project intends to provide an integrated linguistic assessment of the hypothesised migration route of the Tocharians.

Theoretical linguistics seeks to understand the underlying principles of the nature of human language.

The goal of the field of Applied Linguistics is to apply the findings and the techniques from research in linguistics to solve practical language-related problems in society.

Computational linguistics uses computational methods to help answer linguistics questions across a variety of topics.

The one-year master’s in Linguistics is concerned with the knowledge, structure and use of language, studied from a wide range of perspectives. It trains students to systematically identify, describe and analyse language phenomena and to apply this knowledge to a specific area of interest.

In this theme you will be supplied with a firm background in the core of current computational linguistics and a solid comprehension of its neighboring fields.
