I have learned that 'All of us' is All=us, 'it all' is it=us. Then, can I say that all is equal to my money in ' I lost all of my money'. I don't think all is equal to my money but the sentence structure is the same as I took it all ( all of it ) and in some particular context, I think it is possible if they already knew what the 'all' meant and all the speaker had $100. It is so confusing. Could you help me out please. Thank you in advance.
