I'm somewhat confused about the usage and limitations of the ～め suffix that means "somewhat/slightly". I've only ever heard it on a handful of words:
and maybe a few others that I can't recall at present.
1) Can these be used with any イ-adjectives, or only certain ones?
2) Can they be used with ナ-adjectives at all? Can't say I've ever seen one.
3) What are the limitations of its usage? For the イ-adjectives, is ～めに interchangeable with ～く for forming the adverb?
