Hi,
Can you tell me how a person would know if the underlined part is a prepositional phrase or an ellipted subordinate clause acting as an adverbial phrase?
After playing chess, he went on to take a long walk home.
I think 'playing chess' can be said to be a noun phrase that is quite functional as a noun. as shown below . Can a noun phrase like 'playing chess' be used as an object of preposition or only is that it only a 'word' noun can assume that role?
Playing chess is one major activity that prevents me from sleeping at night.
