1. A gathering or reception organized by a person of importance, typically first thing in the morning: “The queen will appear at the main gate for her annual levee on Christmas for which people are waiting very anxiously.”
2. An embankment or dike to prevent flooding: “A new layer of levee is being put on the embankment of the river to save the villages from floods.”
Levy, on the other hand, means to collect or to enlist through an order of legal authority: “The hawkers and peddlers are protesting against the decision the Municipal Committee to levy them with new taxes.”
