Melena is of Greek origin and its meaning is derived from the word "melaina," which translates to "dark." It is often used as a feminine given name, although it can also be used as a surname. Melena has been historically popular in Greece but has gained recognition globally in recent years due to its unique sound and meaning.
The name Melena seems to have had its heyday in the late 1970s and early 1980s, with over 20 births annually from 1974 to 1983. It peaked in 1976 with 29 births. However, it appears that the name's popularity has been declining since then, with fewer than 20 births per year after 1985 and even fewer in recent years, indicating that Melena may now be considered less common.
