------------------------------------- The name's Peter. From New Jersey. 22 years old. Absurdly sarcastic. Read much more in my "about me" by clicking on the link below. =) Side note: Many people are wondering why there are no "non-anon" questions on my blog. It's because I answer them privately so my blog doesn't get overwhelmed with questions. Side side note: I don't do promos. Side side side note: I don't reblog unless the post is something I really feel needs to be seen.
Even though Peter doesn’t have a car because Peter is too cheap to pay for insurance, let’s use “Peter’s car is nice” as an example.
The ’s is used to show singular possession. It’s MY car. You use s’ to show plural possession. For example: “The students’ assignments wreaked of failure.” I’m using s’ because I’m speaking about more than one student. It’s plural.
’s is also used at the end of a word in place of adding “is” after the word. For example: “Peter’s going to the park.” This can be expanded to read: “Peter is going to the park.”
Thus, ’s has two uses (to show singular possession and to replace “is”), while s’ has one use (to show plural possession).
