Possession, contraction, omission.
Not unless you're using a contraction of the words three and is. Example: Three's company! = Three is company Or if you're using it as a pronoun to show possession. Example: Those three's clothes always match!
apostrophe, such as in "could've" for "could have" or "don't" for "do not".
The contractionI'dcan mean either "I would" or "I had."
When you select it, it removes every apostrophe in the story.
A contraction is made of two words with an apostrophe. Note the apostrophe replaces a letter.
If the plural noun has possession, indicate it by using an apostrophe after the S.
The contraction of 'will not' is won't.
You only use an apostrophe in it's when it is a contraction of it is. If you are using ITS to describe something belonging to IT, such as "It was wagging its tail," then the tail belongs to it and so its does not have an apostrophe.
There are three types of apostrophe. The possessive apostrophe, to show that a letter is missing and to highlight a word or phrase, eg 'hasn't', doesn't', 'can't'. The possessive apostrophe would be used in a sentence such as 'The student's work was of a high standard' meaning the work of the student. However if you are using the word students in the plural form, it would be written 'students' work'.
A noun that shows ownership using an apostrophe is a possessive noun.
No, unless your name has an apostrophe in it or you are using it in the possessive.
If you are indicating possession (Achilles' heal) use an apostrophe at the end of the word. If you are simply stating his name, there is no apostrophe.
