apostrophe
Apostrophe s is used to indicate possession for nouns. For pronouns it is used exclusively to indicate the omission of a letter.So you might refer to your cousin's car, but "cousins for life" implies a friendship between multiple (plural) cousins. There would not be an apostrophe there.
An apostrophe is used to indicate a possessive noun, either with apostrophe S for most words or an apostrophe alone for plurals ending in S. It is also used in contractions to indicate letters that have been removed, e.g. he is = he's or do not = don't. It is very rarely used to form plurals that cannot be clearly indicated in the normal fashion (How many this's are in this sentence?)
Use an apostrophe to indicate the following: Possession (cat's tail) Contraction (can't do it) Omission (O'Riley, O'Hara)
The '70s in "1970s" already indicates a plural (decade of the 1970s). Including a punctuation mark between the 's' can make it confusing and redundant.
Yes. The apostrophe is used to show possession, such as in "the dog's collar". it is also used in a contraction to indicate missing letters, such as in "can't", where the letters n and o are missing.
It's up to you to decide what to do. The apostrophe is almost never used to form plurals, but rather possessives. The apostrophe is used to indicate a contraction (it is) in the first sentence.
to indicate missing letters
An apostrophe of omission is used to indicate missing letters in a word, such as in contractions (e.g. can't for cannot). A possessive apostrophe is used to show ownership or possession, such as in "John's book" to indicate that the book belongs to John.
An apostrophe of omission is used for contractions to indicate that there are missing letters.Examples:I will = I'll (the apostrophe takes the place of the letters "wi")should not = shouldn't (the apostrophe takes the place of the letter "o")can not = can't (the apostrophe takes the place of the letters "no")we had = we'd (the apostrophe takes the place of the letters "ha")A apostrophe for possessive nouns is used to indicate that something in the sentence belongs to that noun. A possessive noun indicates ownership, possession, purpose, or origin.Examples:Jack's car = the car belonging to Jackthe girl's smile = the smile on the face of the girlchildren's playground = the playground for childrenthe boss's orders = the orders from the boss
