"Some websites allow categorization, editing, and listening of playlists online." (Wikipedia)
As I know, a gerund can't be followed by the preposition "of". Is this sentence wrong, or is the preposition present here because the word "categorization" is kind of defining (and it needs the preposition "of" after it)?
I've also heard that gerunds can become nouns, if you write them with the definite article, and in this case the preposition "of" is necessary. Is it true? If so, is it the rule I'm looking for?
Thank you for the answers. You all say that it is possible to use the preposition "of" with gerunds, though I've found the opposite information.
Are there any rules for using "of" with gerunds? Is the information given by the links incorrect? If so, is it possible to use "of" with all gerunds followed by direct objects? In this case, is there any sense to operate with the term "verbal noun"? If yes, what would be the difference in using a gerund or a verbal noun?
