In Nepali grammar, the theory of adjectives plays a significant role in understanding the structure and usage of these descriptive words. Adjectives in Nepali are known as “Bisheshan” and are used to modify nouns or pronouns.

The main characteristic of adjectives in Nepali is that they agree in gender, number, and case with the noun they are modifying. This means that the adjective must be in the correct form to match the gender (masculine or feminine), number (singular or plural), and case (nominative, accusative, or oblique) of the noun.

In addition to agreement, adjectives in Nepali can also function as predicates. This means they can stand alone and act as the main element of a sentence, describing the subject. However, when used as predicates, the adjectives must agree with the subject in gender and number.

Furthermore, adjectives in Nepali can be used in various degrees of comparison to indicate superiority, equality, or inferiority. The comparative and superlative forms are created by adding specific suffixes to the adjective base form.

Overall, understanding the theory of adjectives in Nepali grammar is crucial for constructing accurate and grammatically correct sentences. It allows for proper modification and agreement between adjectives and nouns, forming a harmonious and comprehensible language structure.
