Neogrammarians

The Neogrammarians were a nineteenth-century linguistic school that argued sound change operates regularly, subject to identifiable conditions. Their program shaped historical linguistics through systematic comparison of languages.

Neogrammarian hypothesis: The claim that sound laws operate without exception when the relevant phonetic conditions are met. This principle captures the school’s central claim about regular sound change.
Leipzig: A city in eastern Germany that became a major center of nineteenth-century scholarship. The Neogrammarian circle formed around scholars working at Leipzig University.
Hermann Osthoff: A German Indo-Europeanist and Neogrammarian linguist known for work on sound change and analogy. He co-authored the programmatic preface that stated the movement’s principles.
Dialectology: The study of regional and social variation in language, including its geographic distribution. Dialect evidence complicated claims that sound changes were uniform across all speech communities.
Laryngeal theory: A theory that reconstructs consonants in Proto-Indo-European later lost in most descendant languages. Regular correspondences supported a reconstruction whose traces became clearer with Hittite evidence.
Sound change: A systematic alteration in how a language’s speech sounds are produced or perceived over time. Neogrammarians treated it as the central object of historical explanation.
Leipzig University: A public research university in Leipzig, founded in 1409. Its young linguists gave the movement its institutional and intellectual center.
Karl Brugmann: A German linguist whose research on Indo-European grammar became a major model of Neogrammarian scholarship. His comparative work applied regular sound laws to Indo-European languages.
Phonetic law: A proposed regular relation between sounds across forms or languages, often used in historical linguistics. Debates over exceptions tested how strictly the Neogrammarian principle should be understood.
Hittite language: An extinct Indo-European language documented in cuneiform texts from ancient Anatolia. Its discovery supplied evidence for consonants predicted by comparative reconstruction.
