Much of the "Plain" population consisting of groups like the Amish and Old Order Mennonites is bi-lingual, speaking both English and a dialect of German called "Pennsylvania Dutch." A much smaller portion of the non-Plain population of Pennsylvania Dutch descent is also bilingual. Among the Plain, some smaller children speak only this dialect until starting school. The name "Pennsylvania Dutch" is actually a mispronunciation of "Deitsch," or German in the regional dialect. Church services are held in "high German," as opposed to the dialect.
