Lada

Origin: Slavic; Georgian

Meaning: it could mean “young girl” from Slavic mlada, or “bride” or “girl, maid”; the etymology is not clear.

I’ve also seen the name listed as the feminine form of Lado, a Georgian masculine short form of Vladimer from Russian Vladimir meaning “famous ruler” or “peaceful ruler”.

In Slavic mythology, Lada (also known as Lado) is the goddess of love, beauty and marriage, often associated with the other goddesses Freya, Isis and Aphrodite. She’s depicted as a young woman with long golden hair with ears of grain braided in it to represent fertility. Lada is also associated with the summer season and her animals are a cock, a deer, an ant and an eagle, and plants associated with her are a cherry, a dandelion, a linden, and a peony.

However, since Slavic mythology had not been written down in the past, much of the folklore was lost and it’s believed that Lada had never existed in the first place but had been created out of the mistaken belief that the terms used in folk songs (Lada & Lado) were referring to a god/goddess.

Perun

Origin: Slavic

Meaning: “thunder”. I’ve also seen it listed as coming from an Indo-European root word parg meaning “to strike, to slay”, or perhaps coming from another Proto-Indo-European root word perku “oak”.

In Slavic mythology, Perun is the god of thunder and lightning and the highest god in the Slavic pantheon. He’s also associated with the oak tree.

Drago

Origin: Slavic, Italian

Драго (Serbian)

Meaning: from Slavic element dragu meaning “peace” as well as being a short form of names beginning with the element (such as Dragan, Dragomir, or Dragas, etc.)

It’s also an Italian word meaning “dragon”, the Italian form of Latin draco

Draga is its feminine form

Vladimir, Vladimír

Origin: Slavic

Владимир (Russian, Serbian, Bulgarian, Macedonian)

Meaning: from Slavic elements vladeti “rule” and meru “great, famous” meaning “famous ruler”. According to Behindthename, the second element could also be associated with miru “peace, world” so the meaning could also be “peaceful ruler” or “world ruler”. The Vladimír spelling is the Czech and Slovak form of Vladimir.

Milan

Origin: Slavic

Милан (Russian, Serbian, Bulgarian, Macedonian)

Meaning: from Slavic element milu meaning :gracious, dear”. According to Wikipedia, it also has Indian and Latin origins; in Hindu it’s supposed to mean “eager”, “worthy”, or “competitor”, all coming from an expression meaning “a coming together”. In Latin, it’s supposed to mean “eager and laborious”

In Slavic-speaking countries, Milan is strictly a male name with Milana or Milena as its feminine counterparts, although it’s also been used for girls, probably inspired by the city in Italy (whose name comes from a different source- either from Latin or Celtic roots)
