In a separate declaration, distributed by the Ministry of Foreign Affairs of Bulgaria, Sofia indicates that the reference in EU documents to the official language of the Republic of North Macedonia should in no way be interpreted as recognition of the “Macedonian language” by the Republic of Bulgaria.
The declaration also states that: The Bulgarian literary language has six regional written norms (codifications). Three of them are based on dialects, and three on the literary Bulgarian language.
The creation of the “Macedonian language” in 1944-1945 in the former Yugoslavia was an act of secondary codification (re-codification) based on the Bulgarian literary language, further “enriched” with local forms, thereby simulating a “natural” process based on a dialectal form.
