Every predicate in Korean is composed of a stem and an ending. The uninflected form of a Korean predicate is written "stem + 다". A predicate can be inflected to add additional information such as tense or formality. The uninflected form is also referred to as the "dictionary form" or "unconjugated form". A predicate can be a verb, an adjective or a copula.
