I just got to the ~ぬ grammar point and had a question about the exception for conjugating いる:
いる → おらぬ
Is this applicable to both 五段 (godan) and 一段 (ichidan) verbs or just 一段?
For some reason, it’s really hard to find information online about ぬ and ず, and some of it can be misleading. For instance, the information I found about ぬ was written from a classical perspective, so it indicates that it’s only used adnominally, but I’ve seen it used as a predicate in modern Japanese, following the information provided in the grammar point.
