As I understand it, verbals are nouns,adjectives and adverbs which are derived from verbs.
I don't understand if a verbal is indeed one of the three parts of speeches mentioned or a part of speech of itself.
However, the main confusion is whether verbal is a specific term for a practical English grammar or a linguistic term denoting universal characteristics across different languages.
If there are indeed other verbals in other languages how do they differ with the aid of a few examples from different languages?
