In Korean grammar, adjective position plays an important role in sentences, as adjectives can directly modify nearby nouns without needing additional connector words. The key feature of Korean adjectives is that they can function as both adjectives and verbs in a sentence. By conjugating the adjective stem, it can be used to describe the noun or as a complete predicate. By mastering the adjective position and conjugation, Korean language learners can effectively communicate their thoughts and ideas.
