General meaning:
* Éthéré: This is the most direct translation, but it can sound a bit formal and poetic.
* Célestes: This translates to "heavenly" and captures the ethereal feeling of something being otherworldly.
For specific contexts:
* Immatériel: This means "immaterial" and is suitable for describing something that is intangible or spiritual.
* Surnaturel: This translates to "supernatural" and can be used for something that is mystical or beyond the ordinary.

The best translation will depend on the specific context of your sentence. For example, if you are describing a beautiful woman, you might use "célestes" or "ethéré." If you are talking about a spiritual experience, you might use "immatériel" or "surnaturel."
