I thought I've mastered this but I'm getting confused again.
I thought the ~く form of i-adjectives was used when the adjective modifies the noun, e.g.
新しく家を買う
難しく試験した
I think it's named "continuative form" but I'm not sure
Am I correct?. If not, please explain me the correct use.
PS. I think the examples are correct if not please correct me.
