Tatya is an unused word
After centuries, new things appeared in everyday life of people that had their own names. Old items, going out of use, were forgotten. Words with foreign roots were transferred into Russian speech, replacing old obsolete designations.
The origin of the affectionate name of father, father or dad lies in the origins of the Russian language. In a peasant environment, children often called their fathers the simple word "tya".

Among the forgotten definitions are the following: a hryvnia - an ornament around the neck, a brush - a dish (food), a business card - men's clothing, a prototype of a modern jacket, the name of which comes from the fact that they put on a thing to visit.
Origin of the word
Alexander Sergeevich Pushkin made a huge contribution to the expansion of the linguistics of Russian speech. He is given the merit of introducing the word of French origin "dad" into speech. In Russian, the stress is placed on the first syllable. Instead of aunt, tato, father or literary "father", the word "dad" began to be actively used. And the old designations are no longer used.
In etymological dictionaries one can find assumptions about the origin of the word "tya". It is explained as invented by children to designate their father, due to undelivered speech. That is, baby talk marked the parent as a baby.
There are also theories of origin from the Turkic language, Hittite, Greek or Serbian. Each of which has a word with the same meaning and very close pronunciation.
