Having looked it up, no dictionary I can find lists a definition for a hypothetical adjective ❌ deitous, which left me wondering whether by attempting to use ‑ous I perhaps had added the ‘wrong’ suffix to deity in order to convert the noun into its corresponding derived adjective.

This is more of a pedantic question, but just out of curiosity, does anyone know of a word like what I’m describing, an adjectival form corresponding to deity?

That is, an adjective of the form [(root of deity) + suffix], able to be used in sentences such as...

• Many regard the creation of the Universe as a ________ act.
• Magical powers and ________ powers can be seen as a spectrum.
• The people in her empire had no doubt she was ________.
