Hey! I'm new here so please forgive me if I do anything wrong. My question is about adjectives. Verbal adjectives. I'm using an app called "drops: learn Japanese" and in the section "emotions" there is a bunch of adjectives that aren't really い adjectives or な adjectives. I thought that maybe they are verbal adjectives but they don't really follow the pattern for verbs as well. There are adjectives such as: やすまった、ほれている、くつるいだ. For い and な adjectives we add くない or じゃない to make a negative form. How to change these words into negative forms.
