Options:
* Transliteration: Μαρίσα (Marisa) This is the most straightforward approach, using the Greek alphabet to spell the name. It's easily recognizable and pronounceable by Greek speakers.
* Similar-sounding Greek names: Depending on the emphasis you want to put on certain sounds, you might consider names like:
* Μαρία (Maria): This is a very common and popular Greek name, and shares some phonetic similarities with Marissa.
* Ραφαέλα (Rafaela): If you like the "ra" sound at the beginning.
The best choice depends on your preference. If you want a name that's easily understood by Greek speakers and feels Greek, Maria is a strong option. If you want the name to look and sound as close as possible to the original, Marisa (Μαρίσα) is the way to go.
