Bechtel Lecture explains origins of Pennsylvania Dutch.

This article focuses on the origins and linguistic characteristics of Pennsylvania Dutch, as explained by Mark Louden, a Germanic linguistics expert and fluent speaker of the language. Louden traced Pennsylvania Dutch to Palatine German, a dialect from the Palatinate region of Germany, which was adopted by Anabaptist settlers fleeing persecution and later spoken by Amish and Old Order Mennonites in Ontario and Pennsylvania. He highlighted linguistic features such as the use of the diminutive suffix "-li" from Swiss German and vowel pronunciation differences, noting that Pennsylvania Dutch remains grammatically German despite English loanwords. The term "Dutch" in Pennsylvania Dutch derives from the German word "Deutsch" and is unrelated to the Netherlands.
