Original sentence: A kiang is a wild mountain donkey that hops along cliff edges.
Good news: this sentence is grammatically correct. It tells us what a kiang is and what it does.
Two easy ways to say it:
- Same as yours (correct): A kiang is a wild mountain donkey that hops along cliff edges.
- Simpler for young children: A kiang is a wild mountain donkey. It often hops along cliff edges.
Why these are correct (short and simple):
- "A kiang" is the animal we are talking about (the subject).
- "is" and "hops" are the action words (verbs) and they match the subject.
- Adding the word "often" makes the sentence softer, because it says the kiang does this many times but not always.
Meanings: "kiang" = a kind of wild donkey; "hops" = jumps; "cliff edges" = the sides of steep rocks or mountains.
