If you think that Ksenia in an informal setting can only be called Ksenia, you are mistaken. Each Russian name has a great many forms and variants, and the name Ksenia is no exception.
In the Russian language, it is customary to form affectionate diminutive names from the "full", official name that appears in the documents. There are several quite traditional ways of forming such names, but the result is a rather large and varied list from which parents, relatives and just people around can choose a "home" unofficial name for the baby to their taste.
Variants of the name Ksenia, formed by traditional methods
You can go the easiest way: to form names, taking as a basis part of the name "Xen-" and adding to it the traditional diminutive suffixes. It may turn out the following: Ksenichka, Ksenichka, Ksenochka, Ksenichka, Ksenia, Ksensha (as an option - Ksenia), Ksenyok, Ksenya.
The first and most common affectionate name, which is commonly called Ksenia, of course, Ksenia. This name can be made more tender by adding the suffix: Ksyushenka to it. But on the part of the name "Ksyu-" you can also form a lot of interesting options: Ksyunya, Ksyura, Ksyuta, Ksyunechka, Ksyutochka, Ksyura, Ksyurochka, Ksyuksya or just Ksyu. And you can Ksyunya-Kisyunya, if you like.
You can also “discard” the initial letter from the “Ksyu” form and get interesting options starting with “Syu-”: Syut, Syun, Syunyok, Syutushka, Syutok, Syushenka, Syushechka.
And you can also take as a basis the “Ks-” part, adding to it all kinds of word-forming and form-forming elements: Ksana, Ksanochka.
From the last option, the “San” root is formed, and it can also be used to form new affectionate names: Sana, Sanya, Sanya, Sanya, Sanushka, Sanka, Sanya.
You can drop the first letter of the name and form new affectionate names from the part of the name "Sen-". The result is not very common, but also having the right to exist options: Senya, Senyushka, Senechka, Senyura, Senyurusha, Senyushka, Senechka and even Senichka (or even Sinichka)!
Variants of the name Ksenia, formed from "folk forms of the name
It will not be amiss to recall that on behalf of Ksenia two "folk" forms were formed: Oksana (Ukrainian version) and Aksinya (Russian version). So, you can safely call Ksenia as these very names, and their variants.
So, on behalf of Oksana, we form the forms Oksanochka, Oksanushka, Oksanka, Oskanchik, Oksa, etc. And on behalf of Aksinya, you can “make” such affectionate names as Aksinyushka, Aksyuta, Aksyona, Aksyunya, Aksya, Aksyusha and even Asya.
