* Wus: This is the most common and straightforward option. It follows the typical English pluralization rule of adding "s" to the end.
* Wus (pronounced "Woos"): This spelling is less common but can be used if you want to emphasize the pronunciation. It is still a correct plural form, but it is not as widely accepted as "Wus".
Ultimately, the best way to spell the plural form of "Wu" depends on personal preference and context.
