I got two questions regarding the usage of the preposition 'of.'
First is when we say 'a house of cards' do we mean either of or only one of the following?:
- I am referring to a house made of cards
- I am referring to a house that belongs to cards, metaphorically speaking.
1 or 2 or either 1 or 2?
Second question is that when we say 'a cup of coffee,' I am referring to a cup that contains coffee; then the question is whether or not the preposition "of" in "a cup of coffee" works the same way as the "of" in, for example, "Such a jerk of a guy!" or "both of you."
I reckon either 1 or 2 is correct depending on the context; the 'of' in 'a cup of coffee' works the same as when you say "a picture of a bear" looking at a picture that shows a bear.
