In Bulgarian Grammar, the study of adjectives is an integral part of understanding the structure of the language. Adjectives play a crucial role in describing and modifying nouns, and they provide essential information about their qualities and characteristics.

One of the key concepts in the theory of adjectives is that they agree in gender, number, and case with the noun they modify. This means that adjectives must match the gender, number, and case of the noun they are referring to. For example, if the noun is feminine, singular and in the accusative case, the adjective must also be feminine, singular, and in the accusative case.

Additionally, adjectives in Bulgarian can be further categorized into two main groups: qualitative and possessive. Qualitative adjectives describe the qualities of an object, while possessive adjectives indicate possession or relationship.

Understanding the correct usage of adjectives is crucial for learners of Bulgarian, as it ensures accuracy and clarity in communication. Mastering the rules and exceptions of adjective agreement is essential in order to effectively convey information and express oneself fluently in Bulgarian.
