Apostrophes
...and it came to pass that 100,000 English teachers cried out in pain.
Apostrophes:
Use #1: Possessive: Anything belonging to something else.
Example
"The lion's watch is ten minutes slow."
(The apostrophe before the S shows the subject, watch, is owned by the lion)
Exceptions
A- No apostrophes for pronouns like "His" or "Their". (Example: "The boy chucked all his corn.")
B-"Its" is the only word we do not add an apostrophe for a possessive because that would make it a contraction.
(Example: The dragon took its dog for a walk.)
Use#2: Contractions. The combination of two words into a single word, by using an apostrophe.
Example
"The frog fell off the boat, but it's okay." = "The frog fell off the boat, but it is okay."
Other Contractions:
Can't= Can Not
Hadn't= Had Not
Won't= Will Not
Hint: If you cannot tell whether to use an apostrophe for possessive or contraction, try breaking the word into two parts to see if the sentence still makes sense.
(Example: "The serpent ate all of its pie." into "The serpent ate all of it is pie." Doesn't work, so it's possessive and doesn't need an apostrophe.)
