A more thorough explanation:

URE

Ure means custom, practice, or exercise. It comes from the Old French word "oeuvre".

• It was the ure of the tribe to hold a feast after a successful hunt.
• As part of his daily ure, he would meditate for 30 minutes each morning.

In the second example, the person had a daily practice of meditating. In the third example, the company had a regular exercise of holding weekly meetings.
