Is the following sentence correctly punctuated? If not, what is the proper way to correct the sentence?

Peter’s and Linda house is ugly.

*** I would say NO. I think it should written as Peter and Linda’s house is ugly. ***

You're right.

Yes, you are correct. The sentence "Peter’s and Linda house is ugly" is not punctuated correctly. The correct way to punctuate this sentence is: "Peter and Linda's house is ugly."

To explain the correct punctuation, let's break it down:

1. First, we need to indicate that both Peter and Linda possess the house. We achieve this by placing an apostrophe after each name: "Peter's" and "Linda's."

2. Next, since both Peter and Linda possess the same house, we use the plural form of their names by adding an "s" at the end of "Peter" and "Linda": "Peter and Linda's."

3. Finally, we follow this possessive phrase "Peter and Linda's" with the noun "house" to complete the sentence: "the house" or "their house."
