The Basic Idea\n\nUse **'s** with a singular owner: one person, one animal, or one thing.\nExample: \n* “Maria's bag is on the table.”\n* “Tom's jacket is on the couch.”\n\n## 2\\. Core Rules: Singular and Plural Possession\n\nHere is the main system:\n\n* Use **'s** with a **singular noun**.\n    Example: “Maria's bag is on the table.”\n* Use **s'** with a **plural noun that ends in -s**.\n    Example: “The teachers' lounge is very comfortable.”\n\n## 3\\. Irregular Plural Nouns\n\nIf the plural **does not end in -s**, add **'s** as usual.\n\nExamples:\n\n* “The children's books are on the shelf.” → The books belong to the children.\n* “The men's coats are by the door.” → The coats belong to the men.\n\n## 4\\. Two Owners\n\n### Two Owners, One Thing\n\nIf two or more people share one thing, add the **'s** to the second name only.\n\nExamples:\n\n* “Anna and Ben's car is parked outside.” → The car belongs to both Anna and Ben.\n* “Susan and Adam's house is down the road.” → The house belongs to both Susan and Adam.\n\n### Two Owners, Two Things\n\nIf each person owns separate things, add ’s to each name.\n\nExamples:\n\n“Tom’s and Jerry’s houses are on the same street.” → Tom has one house, Jerry has another.\n“Anna’s and Ben’s cars are both red.” → Anna has a red car, Ben has a red car too.\n\n## 5\\. Names Ending in S\n\nWhen a **name ends in s**, the most common written form adds **'s**: **James's** bike, **Chris's** dog. You may also see **James'** or **Chris'** — both are acceptable.\n\nExamples:\n\n* “James's bike is new.” \u002F “James' bike is new.” → Both spellings are correct.\n* “Chris's dog is very friendly.” \u002F “Chris' dog is very friendly.” → Both spellings are correct.\n\n> **Tip:** In everyday writing, James's and Chris's are the most common forms.\n\n## 6\\. Compound Nouns and Phrases\n\nSometimes the owner is a word made of two or more parts joined together, like sister-in-law or mother-in-law. For **compound nouns** (words with hyphens like sister-in-law), add **'s** to the last part. For **phrases describing someone** (like “the bus driver”), add **'s** to the last word.\n\nExamples:\n\n* “My sister-in-law's house is very big.” → The house of my sister-in-law.\n* “My best friend's father works in a hospital.” → The father of my best friend.\n* “The shop owner's keys are on the counter.” → The keys of the shop owner.\n\n## 7\\. Common Mistakes and How to Avoid Them\n\n1. **Don't confuse possessive 's with plural s**\n    * Plural: “The dogs are outside.”\n    * Possessive: “The dog's ball is outside.”\n2. **Be careful with names ending in s**\n    * “Jess's book” → Correct\n    * “Jess book” → Incorrect\n3. **Remember that 's can also mean 'is' as a contraction**\n    * “Tom's happy today.” → Tom is happy today.\n    * “Tom's bag.” → the bag belongs to Tom.\n\n## 8\\. Summary and Key Rules\n\nThe possessive **'s** is **very common**. It can show:\n\n* Ownership (Anna's book)\n* Plural ownership (teachers' lounge)\n* Shared items (Tom and Jerry's house)\n\n> **Tip:** Focus on the **noun that owns something** and decide if it's singular, plural, or part of a compound. Then apply the correct **'s or s'** rule.","en","A2",49,[12],{"id":13,"name":14,"level":9,"language":8,"isCompleted":15,"completionPercentage":16,"totalExercises":17,"completedExercises":16,"vocabularyLists":18},"019aee8a-2300-7913-b1fe-944d135ecfc1","Possessive ’s \u002F s’",false,0,2,[],"2026-01-01T17:45:54+00:00","2026-07-14T17:37:38+00:00",[22],"grammar_exercise_questions_pronouns",[],"\u002Fuploads\u002Fimages\u002Fog_019b7aaa-8462-757d-9d4f-7e901a4fc37b.jpg?v=1784050658",[26,33],{"@id":27,"@type":28,"id":29,"grammarPage":30,"title":31,"instructions":32,"displayOrder":16,"isCompleted":15},"\u002Fapi\u002Fgrammar_exercises\u002F019d30ce-4576-70ae-9a80-de88d22cedb1","GrammarExercise","019d30ce-4576-70ae-9a80-de88d22cedb1","\u002Fapi\u002Fgrammar_pages\u002F019b7aaa-8462-757d-9d4f-7e901a4fc37b","Possessive 's \u002Fs'– Personal Belongings","Fill in the blanks.
