This is silly, really. What is the possessive form of class?

Is it "center of the class’s attention" or center of the class' attention"? I think it's the first one, but I don't know for sure.

Thanks!

Both forms have been used. I prefer the first one class's because that's the way we pronounce it.

Thank you!

You're welcome.

You may either use class' or class's; however, whichever you choose do to, be consistent.

Then it would be Charles', grass', etc.

To determine the correct possessive form of "class," you need to consider whether the word "class" already ends with an "s." If it does, like in this case, there are two widely acceptable options:

1. "Center of the class's attention": This is known as the "s-apostrophe-s" rule, where you add an apostrophe and an "s" after the word, regardless of whether it ends with an "s" or not. This is the more common and recommended form.

2. "Center of the class' attention": This is known as the "s-apostrophe" rule, where you only add an apostrophe after the word if it already ends with an "s." This form is also acceptable, especially if you prefer to avoid the repetitive "s" sound.

Both forms are grammatically correct, but the first option, "center of the class's attention," is more widely used and generally preferred.
