Correct sentence: Every zebra's stripes are unique.
Yes — this sentence is grammatically correct.
Step-by-step explanation for a 7-year-old:
- What it means: "Every zebra" means each zebra one by one. The 's (apostrophe + s) shows the stripes belong to the zebra.
- Stripes is plural: A zebra has more than one stripe, so we say stripes (plural).
- Use the plural verb: Because "stripes" is plural, we use the verb are (not "is"). So we say "stripes are."
- Unique: This word describes the stripes. It means each zebra's stripes are different from every other zebra's stripes.
- Capital and period: The first letter is capitalized (Every) and the sentence ends with a period. Both are correct.
Other ways to say the same thing:
- Each zebra's stripes are unique.
- Every zebra has unique stripes.
Try one: Say or write: "Each kitten's whiskers are long." — check the apostrophe and the word "are."
