When you have a non defining relative clause. eg
Jacks house, which has been on the market for years, has just been sold.
In this sentence the words between the commas are called a non defining relative clause. The clause gives extra (but not essential) information about the subject. The relative clause can be omitted. If the non defining clause is omitted the sentence will still make sense.
When you have a defining clause no commas are used and the clause gives essential information to identify who or what you are talking about.
The house which I showed you last week has just been painted
Here is the sentence with the apostrophes: You can't belive she didn't go?
Inches is shown by two apostrophes (").
Apostrophes and quotation marks can be used interchangeably.
If the apostrophes are appropriately used, there's no problem with using two in one sentence. If possible, try to switch wording to eliminate the need for a possessive. For example: After stopping briefly at Tom's office and George's gallery, the two men and their wives headed to see a Broadway play.
The apostrophes when used in the Latin language serve many purposes. These apostrophes are punctuation marks that sometimes serve as diacritic marks that show possession.
No! Apostrophes are only used with nouns to show possession.
One must have worked - it shows in your question !
That would be a ditto mark.
Apostrophes either show Possession or make a contraction
It should be: The boys' toilets are disgusting.
"Feet" has no apostrophes.
You don't need any apostrophes in this sentence :)
