prepositions after adjectives

So often adjectives are followed by prepositions which cause confusion , something could not be predicted by logics, on have to know them by heart. for example : easy to/for , angry at /with , hard on sb, ok by/with sb, kind of you ....... And it it not an easy task to search all the dictionary .Could you please make a list of those combinations , or direct as to another site.

Hi,
there's no rule, you have to get used to the way verbs, adjectives and idioms are used. If you use dictionaries like these...

Try looking up "angry" for example, it's easy to see how it's used. They both show what prepositions to use and how to use what you want in a sentence.
Hope it helps, somehow.
