Middle Bulgarian

This period of the language exhibits significantly different morphology from earlier periods, most notably in the complete disappearance of the locative, instrumental, and genitive cases.

Analytical tools for the gradation of adjectives and adverbs appear.

[2] A language of rich literary activity, Middle Bulgarian served as the official administration language of the Second Bulgarian Empire, the successor principalities of Walachia and Moldavia (until the 19th century) and the Ottoman Empire (until the 16th century).

[4] In the Middle Bulgarian language there is an increased use of prepositions in the place of the dative, genitive and instrumental cases.
