Synonyms for Empower/Empowerment?

I am looking for some sources/books/websites/suggestions that may help me find synonyms or closely related words to the words “empower” or “empowerment.”

Also, would like some help figuring out if there are any ancient languages that have words that closely relate to empower or empowerment.

Only word I have come up with is “endunamoo” (Greek).

Appreciate any help.

Thanks…
