 ::Not just difficult: impossible. Some contributions to that discussion hinge on distinguishing a "language" from a "dialect", a distinction without scientific basis. To quote Dialect#Dialect_or_language [refs & flags deleted, text abridged, bolding added; my comments italicized in square brackets]: 
 ::*There is no universally accepted criterion for distinguishing a language from a dialect. A number of rough measures exist, sometimes leading to contradictory results. Some linguists do not differentiate between languages and dialects, i.e. languages are dialects and vice versa. The distinction is therefore subjective and depends on the user's frame of reference. Note also that the terms are not always treated as mutually exclusive… 
 ::*Language varieties are often called dialects rather than languages … [four causes listed] 
 ::*Anthropological linguists define dialect as the specific form of a language used by a speech community. From this perspective, everyone speaks a dialect. Those who identify a particular dialect as the "standard" or "proper" version of a language are seeking to make a social distinction. … 
 ::*The status of language is not solely determined by linguistic criteria, but it is also the result of a historical and political development. [Examples] 
 ::See also Dialect continuum.
