Who is the 11th archangel?

In various spiritual and religious traditions, the term "archangel" typically refers to high-ranking angels, but there is no universally recognized list of archangels that includes an "11th archangel." The most commonly acknowledged archangels in Judeo-Christian traditions include Michael, Gabriel, Raphael, and others, usually totaling seven or eight. Some esoteric beliefs or modern interpretations may introduce additional names, but these are not standard. If you have a specific tradition or interpretation in mind, please provide more context for a more accurate response.
