I have learnt something about deverbal nouns before.
a)These readings are quite interesting (Here it means books,refers to something)
b)I did some reading of history books(Here it means the act, it has verbal characteristics)
But some words in dictionary are quite confusing, please help check the following sentences:
Dealing: business activities, the relations that you have with somebody in business; eg: I knew nothing of his business dealings (Here the meaning of "dealing" should be the same with a)? refers to something?)
Greeting: something thay you say or do to greet people(here should be the same with a)?
Swimming: an activity or sport(Here should be the same as b)? Because it has some verbal characterisitcs)
Please help me to check my thought.
