However, you could get creative and consider these options, though they may not be conventional:
* Phonetic variations:
* Promis
* Promyse
* Adding a "y" for a softer sound:
* Promisy
* Using a different letter for the "s" sound:
* Promice (using a "c" for a more "k" sound)
Remember, these are just suggestions, and ultimately the best way to spell your child's name is whatever you feel is right and fits your personal preference.
