A trend in many Western European languages is to gradually become more analytic and less synthetic over time. Why is that? Many modern-day languages are descended from much more heavily inflected ancestors (English to Old English). However, in some places, languages still remain heavily inflected just like their ancestor(s). Can a moderately analytic language, like English, ever become more synthetic over time and re-develop case endings (taking into account all the communication technology available today)? If so, how (where would we get case endings, etc.) . If not, is there some constant/law which would say that a slow shift from a language being analytic to synthetic in this modern era can never happen?
