Vadim

Origin: Russian

Meaning: it’s the Russian form of Bademus, a Latinized form of a Persian name, meaning unknown. It’s also been linked to Slavic Vadimir meaning “accuse + peace, world” from Slavic elements vaditi (accuse, to slander, to blame) and miru (peace, world).

Vadik is a diminutive form of the name.

Variants: Vadym (Ukrainian); Vadzim (Belarusian)

Vidya

Origin: Indian

विद्या (Hindi, Sanskrit)

Meaning: it means “knowledge, science, learning” in Sanskrit. It was also one of the epithets of the Hindu goddess Saraswati.

Also it’s listed as a feminine name on Behind the name, I’ve seen it used as a masculine name, making it a unisex name.

Variants: Widya (Indonesian); Vidyā, Vidhya

Vivaldi

Origin: Germanic, Latin, Italian

Meaning: it could be a Latin form of Vivaldus meaning “power, strength in combat” from Old German elements wig (fight, battle, warrior) and walda (might, power).

I’ve also seen it listed as coming from Latin vita meaning “life”.

Vivaldi is an Italian surname, most famously worn by Antonio Lucio Vivaldi, a Baroque composer whose best known work are The Four Seasons, a four violin concerti.

Vanessa

Origin: English

Meaning: a famous name created by the author Jonathan Swift for his poem Cadenus and Vanessa (1713). He created it by taking the first three letters of his lover’s surname (Esther Vanhomrigh) and adding the pet form Essa. Vanhomrigh is a Dutch surname and van means “from”, referring to a habitational surname, while Esther either means “star” or is from Ishtar, of unknown meaning, so I guess you could stretch the meaning to be “from the stars”.

Variant: Vanesa (Czech, Slovak), Vinessa

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.
