If your land bordered a royal forest, there could be some confusion about where your land started and the royal forest ended. By performing a perambulation, you could gain some degree of ownership over disputed forest tracts, although your use of them would be restricted by forest laws. Such regained forest property was called a purlewe (or as it was later spelled, purlieu), which derives from the Anglo-French word for "perambulation."
That word was all over a redvector CEU I completed last week.
