(French parque, that is, locus inclusus) is a large extent of ground enclosed and privileged for wild beasts of chase, by the king's grant or prescription.

Manwood defines a chase a privileged place for beasts of venery, and other wild beasts of the forest and chase, tam sylvestres quam campstres. A park, therefore, differs from a chase or warren in this, that it must be enclosed; for if it lie open, this is a good cause of seizure by the king, as a thing forfeited.
