Musa is of Arabic origin, meaning 'saved from water'. It is also found in various other cultures and languages, including Swahili and Turkish. In Islamic tradition, it refers to Moses, the prophet who played a significant role in leading his people out of Egypt and receiving the Ten Commandments on Mount Sinai.
The name Musa appears to have had a resurgence in popularity between the years of 1918 and 1922, with eight births each in those two years, which was more than any other decade recorded. However, the overall total of thirty-one births over these five years suggests that it was not a particularly common name during this period.
