This is a companion discussion topic for the original entry at https://english.best/questions/preview/1221-what-is-one-of-the-short-forms-of-the-name-vladimir?_ga=2.207432595.1448967283.1645427897-722513222.1643731551
The short form of the name “Vladimir” is Vova. In Russian. we also use Volodja as well as Vovan. Vovan is kind of slang among young people.
Funny thing is that many non-Russian speakers think that “Vlad” is short for “Vladimir”, which is why they call Vladimir Putin “Vlad” to his chagrin
I thought this also, including online friends named “Vlad”. I guess I know better now.
