Milena is the feminine of Milan — from the Slavic mil, meaning "gracious," "dear," or "beloved." Used across Czech, Slovak, Bulgarian, Serbian, and Croatian.
Milena entered the U.S. top 1000 in 2014 and has been rising. Milena Jesenská (1896-1944), the Czech journalist and translator of Kafka, gave the name literary visibility.
Milena reduces to eight — the number of warm Slavic devotion.
