Malechi is of Hebrew origin and means "disease" or "sickness". It is often considered an unusual name, offering a unique identity to those who bear it. The name does not have any specific cultural significance or traditional uses outside of its biblical context, where it appears as the name of one of King David's sons in the Old Testament (2 Samuel 12:35). As a given name, Malechi is rare and has gained little recognition beyond religious circles.
"The name Malechi experienced a notable spike in popularity between 2006 and 2008, with twelve births recorded during that period. Prior to this peak, the name maintained steady growth, with five births annually from 2002 to 2003 and again from 2014 to 2020. However, there was a decline in popularity after 2008, as seen by the fewer births recorded each year until it reached another peak in 2020 with five births."
