The word "eischen" is a surname that originates from the German language. It is often pronounced as /ˈaɪ.ʃən/ in English, with the "ei" making an "eye" sound, the "sch" making a "sh" sound, and the "en" making an "uh" sound. This pronunciation is different from the German pronunciation, where the "ei" makes an "aye" sound and the "ch" makes a guttural "kh" sound. The difference in pronunciation between languages is due to the varying phonetic rules and sounds of each language.
