The Difference Between Language and Dialect

The line between language and dialect is a little fuzzy yeah it's like me. Trying to avoid the dialects diverging into different languages because there are no native speakers of these language of these languages you can't do the mutual intelligibility test on a conlang so you might you have to. staged um now sound changes that occur in staged stages if you put some of those in those could be interestingbecause different dialects could be at different stages as well.
