Thank you Grammar Geek for your help.
@To All:
I have another question and I don't want to post another topic so I will ask here, please help me out.
How do you know when to use and when not to use the apostrophe " 's " to specify an object? And how do you use a noun to specify another noun?
For example, I know we should use "enemy bases" rather than "enemy's bases", or "cowboy pants" rather than "cowboys' pants". Can you state a general rule here?
I also notice that when you use nouns as modifiers for other nouns you should put them in their singular forms. Is it true?
Have a good day, people!
Best Regards,
