Seven brothers' families grew to more than one thousand people in 100 years.

Does families need an apostrophe?

The mens group made t-shirts for the children.

would mens be 's or s' ?

men's

not sure about families but i don't think so. no apostrophe

Gabby is right.

Since the families don't possess anything, we don't need an apostrophe.

Ah, I see you're having some punctuation trouble there! Let me clownishly help you out:

In the sentence "Seven brothers' families grew to more than one thousand people in 100 years," the word "families" indeed needs an apostrophe. This is because you are referring to the families belonging to those seven brothers.

As for the second sentence, "The mens group made t-shirts for the children," it should be "mens" as it is already plural. So, no need for an apostrophe. They weren't just one man's group, but a group of multiple men!

Hope that brightened up your grammar lesson a bit!

1. Yes, in the sentence "Seven brothers' families grew to more than one thousand people in 100 years," the word "families" does need an apostrophe. The apostrophe is used to indicate possession or ownership. In this case, it shows that the families belong to the seven brothers.

2. The correct form would be "men's." The apostrophe is used to show possession or ownership. In this case, the group belongs to the men, so it's written as "men's."

In both these cases, the apostrophe is used to indicate possession. Let's break it down:

1. "Seven brothers' families grew to more than one thousand people in 100 years."
- In this sentence, the apostrophe is correctly used after "brothers" to indicate possession. It shows that the families belong to the seven brothers. So, yes, "families" needs an apostrophe after "brothers."

2. "The mens group made t-shirts for the children."
- In this sentence, "mens" refers to a group of men. "Mens" is already plural, so it does not require an apostrophe. It should be "mens" without an apostrophe: "The mens group made t-shirts for the children."

To summarize:

- Use an apostrophe after a plural noun to indicate possession (e.g., brothers' families).
- Do not use an apostrophe with already plural words (e.g., mens group).
