Apostrophe Quiz: Which Sentence Is Correct? Cheat Sheet
- Possession for singular and plural nouns - When a single noun owns something, add 's (e.g., "the dog's bone"); for plural nouns ending in s, just tack on an apostrophe (e.g., "the dogs' bones"). This little mark keeps ownership crystal clear and your writing sharp! Learn more about possession rules owl.purdue.edu
- Possession for plural nouns not ending in s - If a plural noun doesn't end in s (like "children"), add 's to show possession (the children's toys). This rule ensures every owner, big or small, gets properly credited! Dive into non‑s plural possession owl.purdue.edu
- Contractions signal missing letters - Contractions like can't (cannot) or it's (it is) use an apostrophe to snip out letters and keep things breezy. They give your writing a friendly tone - just watch for misuses that can trip up your reader! Get the contraction lowdown owl.purdue.edu
- Possessive pronouns don't get apostrophes - Words like its, yours, theirs show ownership without an apostrophe. Remembering this prevents mix‑ups between its (belonging) and it's (it is), keeping your sentences typo‑free! Explore pronoun possession owl.purdue.edu
- Forming plurals of letters (but not numbers) - To pluralize lowercase letters, add 's (mind your p's and q's), but skip the apostrophe for decades ("1960s") or capital letters ("As and Bs"). It's the difference between clarity and clutter! See letter‑plural rules owl.purdue.edu
- Possessives of singular nouns ending in s - Style guides vary: you can write James's book or James' book. Pick a style and stick with it throughout your work so your writing feels consistent and polished! Check out style variations owl.purdue.edu
- Avoid apostrophes for normal plurals - Plurals of nouns, acronyms or numbers (CDs, 1990s) don't need apostrophes. Keeping them apostrophe‑free avoids the dreaded "banana's" mistake and looks sleek on the page! Master proper plurals owl.purdue.edu
- Joint vs. individual possession - When two people share something, add 's to the last noun only (Ben and Jerry's ice cream). For individual ownership, give each person their own 's (Caitlyn's and Celia's bikes). It's teamwork vs. solo style! Learn possession partnerships pittstate.edu
- Omitting numbers in dates - Use an apostrophe to drop the initial digits of a year ('80s for 1980s). It's a stylish shortcut that keeps your historical references tight and snappy! View date formatting tips niu.edu
- It's vs. its - It's (it is) needs an apostrophe; its (belonging to it) does not. This classic mix‑up can trip even seasoned writers - double‑check to keep your meaning on point! Clarify it's vs. its owl.purdue.edu
