If I am in doubt and I look up the dictionary, I would use "many" if the word has an -s right? If the word doesn't have an -s, does that mean it cannot be plural? Which means that I canno use 'many' with the word right?
I looked the word 'money' up at dictionary.com:
1. Sums of money, especially of a specified nature. Often used in the plural: state tax moneys; monies set aside for research and development.
I don't get the bold part? How does it make money plural?
monies/moneys, specifically in Business, refers to sums of money directed to/from more than one source. :D
