Apostrophes with Nouns  \nApostrophes make nouns possessive.  \nTo make singular noun possessive , add apostrophe + -s.  \n• The boy’s coat = the coat belonging to the boy  \nThis rule holds true even when a singular noun ends in-s.  \n• The dress’s buttons = the buttons on the dress To make a plural noun possessive , add-s + apostrophe.  \n• The books' pages = the pages of the books  \nIf the singular form of a noun ends in-s , add-es + apostrophe to the make the plural form possessive.  \n• The dresses' buttons = the buttons on the dresses  \nSome nouns are irregular—that is , their plural versions are not formed by adding-s to their singular forms , e.g. , foot, feet; goose , geese; child, children.  \nTo form the possessive of such nouns , add apostrophe + -s. Because the plural form is already different from the singular form , the two types of possessivescan be easily distinguished.  \n• The goose's feathers = the feathers of the goose (sing.)  \n• The geese's feathers = the feathers of the geese (pl.)  \n• The child's game = the game the child is playing (sing.)  \n• The children’s game = the game the children are playing (pl.)  \nComplete SAT/ACT Grammar Rules 3  \nB. Apostrophes with Pronouns  \nNo apostrophe = possessive  \nIt’s vs. Its  \nIt’s = it is  \nIts = possessive of it; followed by a noun Its’& its’s = do not exist  \nIncorrect: London is a city known for it’s (it is) many tourist attractions.  \nCorrect: London is a city known for its many tourist attractions.  \nIncorrect: London is a popular tourist attraction; in fact, its among the most visited cities in the world.  \nCorrect: London is a popular tourist attraction; in fact, it’s among the most visited cities in the world.  \nNote that on the ACT, the correct answer is almost always its because this is the form students tend to misuse most frequently.  \nThey’re vs. Their vs. There  \nThey’re = they are  \nTheir = possessive of they and plural of its; followed by a noun There = a place  \nCorrect: London and Paris are two of the most famous cities and Europe, and they’re (they are) known for having many tourist attractions.  \nCorrect: London and Paris, two of the most famous cities in Europe, are known for their many tourist attractions.  \nCorrect: In the nineteenth century, Paris was considered the capital of theart world because so many famous painters lived and worked there.  \nComplete SAT/ACT Grammar Rules 4  \n________________________________________________________________________  \nWho’s vs. Whose  \nWho’s = Who is  \nCorrect: Barbara McClintock is a scientist who’s (who is) best known for her discovery of “jumping” genes.  \nWhose = Possessive of who; followed by a noun  \nCorrect: Barbara McClintock is a scientist whose discovery of \"jumping\"genes helped earn her the 1983 Nobel Prize in Physiology or Medicine.  \nNote that whose , unlike who , can be used for both people and things/places.  \nCorrect: London is a city whose many museums , palaces , and  \nmonuments make it a popular tourist destination.  \nII. Semicolons and Periods  \nA. Semicolon = Period  \nSemicolons and periods are used:  \n1. Between two complete sentences  \nCorrect: London is an old city; it was first settled around 47 A. D.  \n2. Before conjunctive adverbs such as however, moreover, and therefore when they are used to begin a clause.*  \nCorrect: London is an ol","cbCaisYx4zQ0Sx1k","https://ap.wps.com/l/cbCaisYx4zQ0Sx1k","pdf",2777415,28,"English","# Apostrophes\n## Apostrophes with Nouns\n## Apostrophes with Pronouns\n# Semicolons and Periods\n## Semicolon vs Period\n# Commas\n## Comma with Coordinating Conjunctions (FANBOYS)","[{\"question\":\"How do you form singular and plural possessive nouns with apostrophes?\",\"answer\":\"For singular nouns, add apostrophe + -s.
