い-Adjective (Predicate)

This point shows how to use i-adjectives to describe the subject as a predicate. In polite speech, attach です to the i-adjective stem (drop い and add いです? The correct form is directly the i-adjective stem followed by です, e.g., 暑いです). In casual speech, the plain form serves as the predicate (e.g., 暑い). You can also form past and negative predicates by changing to the appropriate endings.
