Here are three simple ways to say the sentence:
- The clever fox walks back over its footprints to hide them.
- The sly fox goes back the same way to cover its tracks.
- The smart fox walks backwards along its path so no one can see where it went.
What it means (easy steps):
- The fox left footprints when it walked.
- It walks back over the same spots to mix up or hide those footprints.
- That makes it hard for others to follow or find the fox.
