[Nyororin]

I find it interesting that you couldn`t understand 払える and もらっとる, but had no questions about いらん, which also wouldn`t appear in a dictionary.

I know nothing about "ichidan" or "godan" words (First time I`ve ever heard those terms, in fact.)

The える ending on 払う is meaning "ability to". The form depends on the verb itself (For example; ける for く verbs - 歩ける for 歩く, れる for る verbs - 食べれる for 食べる).

もらっとる is a dialect for of もらってる. The おる form is sort of country sounding, and very informal. (It`s shortened from もらっておる - もらってる is shortened from もらっている)
