Filipinos, for the Nth time...
Bisaya is not a dialect.
Cebuano is a language
Bisaya is a language
Tagalog is a language
Ilokano is a language
Hiligaynon is a language (Ilonggo refers to the people)
But, Batangenyo is a dialect of Tagalog. Boholano and Bisaya are dialects of Cebuano.
When someone from Davao (Bisaya) speaks to someone from Cebu (Cebuano), they will still understand each other. Why? Because they speak the same LANGUAGE.
