Here's why it's so difficult to pinpoint a number:
* Continuum: Dialects blend into each other geographically, forming a continuum rather than distinct categories.
* Variation: Within each dialect, there's further variation based on factors like age, social class, and ethnicity.
* Mutual intelligibility: The key criteria for defining dialects is mutual intelligibility. If speakers from two areas can understand each other, they are often considered to be speaking the same dialect. However, this can be subjective and vary based on individual experience.
Instead of focusing on a specific number, it's more helpful to understand the diversity and richness of the English language and how dialects contribute to its vibrant character.
