Mikes car needs a new muffler and new brakes. (Which word needs an aposterphy?)

I presume you mean 'apostrophe'

The apostrophe here will show possession. The car belongs to Mike thus

Mike's car needs a new muffler and new brakes.

To determine which word in the sentence needs an apostrophe, we can break it down and look at each word individually.

The sentence is: "Mikes car needs a new muffler and new brakes."

Let's analyze each word:

1. "Mikes" is the possessive form of the name "Mike." In this context, it indicates that the car belongs to Mike. However, it is important to note that "Mike's" should have an apostrophe (') to show possession. Therefore, the correct version should be "Mike's car."

2. "Car" is a noun, and in this case, it doesn't require an apostrophe.

3. "Needs" is a verb and does not need an apostrophe.

4. "A" is an article and doesn't require an apostrophe.

5. "New" is an adjective and doesn't need an apostrophe.

6. "Muffler" is a noun and doesn't require an apostrophe.

7. "And" is a conjunction and doesn't need an apostrophe.

8. "Brakes" is a plural noun and doesn't require an apostrophe.

Therefore, the word that needs an apostrophe in the given sentence is "Mikes," which should be corrected to "Mike's car."
