Please read the definition of nickname in English dictionary and try to see that the forms you've mentioned here better call short names not nicknames.

I support Aud.

Short explanation.

The forms you've mentioned here <em>in Russian </em>called short names, not nicknames.

Long explanation.

Internet shows English "nickname" as a term that contains both nickname and short name functions, without clear boundary. That it is quite confusing for Russian speakers because the term "nickname" has a quite a different meaning in Russian language. In Russian we also have a separated term "short name" ( or as Aud reffer short form of ) that is not a "nickname".

To avoid this cross language ambiguity, I'd rather use both terms separately , at least when it comes to Russian-English-Russian conversions.

Thank you for your note.

But actually this post is about Russian, not English and there are different opinions about this and the people I consulted with recommended to use the word "nickname" in this sutuation.

As it comes from the discussion they call it a short form of an official name. Not a nickname.

Вова, он же Болодя ))) А в следующий раз будет из короткого имени восстановить полное, типа Кеша -->> Иннокентий или Геннадий; Дуня -->> Авдотья или Дарья ? ^^^
