It's likely a combination of "umuntu" (person) and "umxhasi" (someone who teaches or guides), potentially implying something like:
* Humanist: This is the closest English equivalent in terms of the broad concept of focusing on human values and concerns.
* Humanitarian: This emphasizes the focus on helping and supporting other humans.
* Educator: This highlights the role of teaching and guiding others.
To get a more accurate understanding, you'd need more context. What is the word being used to describe? What is the surrounding text or conversation?
