How would you say goddess of the moon in Gaelic?

There isn't a single, universally accepted term for "goddess of the moon" in Gaelic. Gaelic (covering Scottish Gaelic and Irish Gaelic) didn't have a single, overarching moon goddess like some other pantheons. The moon's personification varied regionally and across different mythologies within those cultures.

To create a phrase, you'd need to combine words. Here are some options, bearing in mind nuance and regional differences:

* Scottish Gaelic: You could potentially say something like "Ban-dia na gealaich" (Ban-dia = goddess, na = of, gealaich = moon). This is a direct translation, but it lacks the mythological depth.

* Irish Gaelic: Similarly, "Bandia na gealaí" (Bandia = goddess, na = of, gealaí = moon) would be a direct translation, but doesn't capture the specific mythology.

It's important to note: These are literal translations. A more accurate and evocative phrase would require a deeper understanding of the specific mythological context you're aiming for. You might need to consider specific moon goddesses mentioned in myths or legends from a particular region to create a more fitting term.
