Earlier quoted context omitted.
I don't speak Armenian, but I dated an Armenian woman once, and she told me they have words for familial relationships that we didn't really have concepts for in English.
In Swedish our words for many relationships follow a very simple system of composing relationships. A few examples: Mor = mother Far = father Bror = brother Morfar = mother's father Farfar = father's father Farmor = father's mother Farfar = father's father Farbror = father's brother Morbror = mother's brother ...
Faster = fathers sister
Moster = mothers sister
You can also use tante (aunt) about these
A farbror or morbror is often called an onkel (uncle).
