Here are three easy ways to say that sentence, and short explanations so a 6-year-old can understand:
- The deer is light and quick, so it moves easily through the thick bushes.
Meaning: the deer doesn't bump into things and it moves fast through the bushes.
- The deer runs fast and slips through the bushes without trouble.
Meaning: the deer is speedy and can get through the bushes nicely.
- Light on its feet and very quick, the deer goes through the thick forest bushes.
Meaning: the deer walks and runs carefully and fast among the many bushes.
Words explained:
- Light — not heavy or moving gently so it doesn’t knock things over.
- Fast — runs or moves quickly.
- Thickets — lots of bushes close together in the forest.
If you want, I can make even simpler versions for very young children or a picture idea to show the meaning.
