Correct sentence: A tiger’s stripes help it hide in tall grass.
This sentence is grammatically correct. Here’s why, step by step — explained for a 7-year-old:
- "A tiger’s stripes" means the stripes belong to one tiger. The apostrophe + s (’s) shows ownership — the stripes are the tiger’s.
- "stripes" is plural (more than one stripe). Because the word is plural, we use the verb help (not helps).
- "it" is a word that means one animal (the tiger). So we say "help it hide" — the stripes help that one tiger hide.
- "hide in tall grass" is a good phrase that tells where the tiger hides.
Other ways to say the same idea:
- A tiger's stripes help the tiger hide in tall grass. (Same meaning, repeats "the tiger".)
- For more than one tiger: Tigers' stripes help them hide in tall grass.
Great job noticing the sentence — it’s already correct!
