What does the word 'of' mean in the following sentence? And could you explain using another example with the word 'it'?
*Bassanio offered Shylock twice as much money as Antonio had borrowed.
But Shylock would not accept anything but the pound of flesh.*
Thanks in advance.
I don't really understand the question. Shylock required an amount of flesh equivalent to a pound in weight. It was a cruel insistence on the terms of a contract. 'Of' means 'of'; there's no point trying to find an equivalent word; all you can do is see how it's used in real phrases (like 'pound of flesh' or 'tube of toothpaste' - where the two "of"s have clearly different meanings).
The phrase 'pound of flesh' is used now with reference to any harsh insistence on the precise terms of an agreement. 'I told him I didn't have it right then and there, and asked for another week to pay; but he would have his pound of flesh.'
