Apostrophes are used for:
* Possession: Shows ownership (e.g., "the dog's bone").
* Contractions: Shorten words by combining them (e.g., "don't" instead of "do not").
* Plurals of letters or numbers: (e.g., "Mind your p's and q's", "There are two 5's in that number").
Quotation marks are used for:
* Direct speech: Enclose the exact words someone said (e.g., "Hello," she said).
* Titles of short works: (e.g., "The Raven" is a famous poem).
* Words used in a special sense: (e.g., The word "love" can have different meanings).
Confusing the two can lead to errors and miscommunication. For example:
* "The dogs bone" (missing apostrophe) implies the bone belongs to multiple dogs.
* "The dogs' bone" (correct use of apostrophe) shows that the bone belongs to one dog.
* "The dog's bone" (correct use of apostrophe) shows that the bone belongs to one dog.
Remember:
* Apostrophes are primarily for showing possession and contractions.
* Quotation marks are for direct speech and titles, and sometimes to highlight a word or phrase.
