An abscond is when someone runs away or disappears without explanation.
Imagine you're at work and your boss says that one of your colleagues has absconded with some important documents - this means they took them and left the office, but no one knows where they went or why. People often abscond to avoid trouble or consequences for something they've done.
To flee, often secretly; to steal away, particularly to avoid arrest or prosecution.
Example: The thieves absconded with our property.
