* Malaika: This is the most common and general translation for "angel." It's used in both religious and non-religious contexts.
* Mtume: This word literally translates to "messenger," but it can also be used to refer to an angel, particularly in a religious context. It is often used to describe the messengers of God.
So, you can use "malaika" for a general angel, and "mtume" if you are specifically referring to a messenger angel.
