Okay, I've kept quiet for a very long time. Here is a SIMPLE grammar lesson we should all understand if we've graduated from high school (actually before that, but I'm being graceful).
To make something plural, just add an -s or -es to the end of the word. Plural means more than one.
For example: The Andersons (there are five of us).
The computer screen (there is just one screen).
Got it? I hope so.
To make something possessive (as in showing ownership), that's when you get down and dirty with the apostrophes. Yes, even if the noun has an "s" at the end of the word, you just add an 's, unless it's plural already. See the examples below.
Jesus's word (the Bible, if you didn't know)
Krista's family (the family belongs to Krista)
Krista and Stefan's family (the family belongs to both of them; only the last noun
gets the apostrophe!!)
Students' desks (more than one student and more than one desk)
The Andersons' house (the house belongs to the Andersons; there are 5 of us)
The dog's collar (one dog, one collar)
The dogs' collars (more than one dog, more than one collar)
The Hicks Family (Their last name ends in "s"; NO NEED for an apostrophe)
You need an apostrophe for contractions, also. A contraction is two words made into one word. The apostrophe signifies the letter that has been omitted.
Can not = can't
is not = isn't
it is = it's
will not = won't
*** Its is a pronoun which refers to something that is not human (animal or object). It's not always a contraction. It's and its are two different words! You should probably learn the difference if you have a job or want a job.
Now, go fix your blogs.
