پژوهشگر

Ludwig Maximilian University of MunichGermany

Ander Egurtzegi serves as an Associated Researcher at the Institute of Phonetics within the Faculty of Languages and Literatures at Ludwig Maximilian University of Munich. His scholarly identity centers on empirical investigations of sound systems through historical and typological lenses, with uninterrupted publication activity from 2009 to 2018 demonstrating active academic engagement. His research program systematically explores phonological evolution in Basque dialects, particularly Zuberoan. Core investigations include metathesis phenomena, vowel nasalization patterns, aspiration mechanics, and contact-induced changes like /u/-fronting. Methodologically, he combines spectral phonetic analysis with historical reconstruction and cross-linguistic comparison, frequently examining how phonetic conditioning drives sound change. His work bridges theoretical phonology with documentary linguistics, preserving endangered dialectal features while testing universalist claims. Analysis of his 15 most recent publications reveals three dominant thematic clusters: (1) Vowel system evolution (raising, nasalization, fronting) in Eastern Basque dialects; (2) Consonantal processes including obstruent loss, aspiration, and metathesis; (3) Interdisciplinary connections between phonology, etymology, and language contact—particularly Basque-Celtic lexical relationships. His outreach efforts demonstrate commitment to public dissemination of linguistic science, examining how speech errors contribute to language change.
