Compound Nouns: A compound noun is a single noun that is formed by combining two or more words Example: footprint doghouse backpack __ Possessive Nouns: A possessive noun shows ownership or relationship. Example: hiker's boots Karen's car __

Let's expand on Compound and Possessive Nouns with further examples and explanations:<br /><br />**Compound Nouns:**<br /><br />As stated, a compound noun combines two or more words to create a single noun with a new meaning. These words can be combined in a few different ways:<br /><br />* **Closed Compounds:** These are written as a single word. Examples: `sunlight`, `keyboard`, `toothbrush`, `notebook`, `watermelon`<br />* **Hyphenated Compounds:** These use a hyphen to connect the words. Examples: `mother-in-law`, `six-pack`, `check-in`, `dry-cleaning`<br />* **Open Compounds:** These are written as separate words but function as a single noun. Examples: `post office`, `living room`, `full moon`, `ice cream`<br /><br /><br />**Possessive Nouns:**<br /><br />Possessive nouns demonstrate ownership or a relationship. They are typically formed by adding an apostrophe and an "s" ('s) to the noun. Here's a breakdown with more examples and rules:<br /><br />* **Singular Nouns:** Add 's. Examples: `dog's bone`, `cat's toy`, `James's book` (Note: While sometimes the second "s" is omitted after a name ending in "s," the form with 's is generally considered correct and more consistent.)<br />* **Plural Nouns ending in s:** Add only an apostrophe after the existing "s". Examples: `dogs' bones`, `cats' toys`, `students' projects`<br />* **Irregular Plural Nouns (not ending in s):** Add 's. Examples: `children's books`, `men's clothing`, `women's rights`<br />* **Joint Possession:** When two or more nouns possess the same thing, add 's only to the last noun. Example: `Jack and Jill's pail` (They share one pail.)<br />* **Individual Possession:** When two or more nouns possess separate things, add 's to each noun. Example: `Jack's and Jill's pails` (They each have their own pail.)<br /><br /><br />Understanding the difference between compound and possessive nouns is important for clear and grammatically correct writing. Compound nouns create *new* nouns, while possessive nouns show *ownership* of existing nouns.<br />
