Language Attrition As A Social Process, Or Barzilay

Master's Projects and Capstones

Language attrition is a process in which the gradual decline in proficiency of a language occurs when another language becomes more prominent among individuals, families, and broader societies. This shift often occurs not by choice but by necessity, as speakers are expected to adapt to the other language in educational settings, for employment, and to conform to societal pressures in their new environments. Although language attrition is often described as an individual loss of proficiency, contemporary research reveals a far more complex picture—one shaped by factors that determine which languages are valued and which fade into obscurity. These forces collectively …
