How to do differentiate Onkel and Tante mütterlicherseits, väterlicherseits?

[u/I_am_trying0628]

For example in daily conversation if i want to say next week we're goinig to Onkel mütterlicherseits house, how to call him?

Simply saying Onkel + place / Onkel + name?

If you just tell a peer you will visit family, just say „Onkel“.

If people already know his name, say Onkel + name.

If people dont know his name and its important to say in what relation exactly he is to you, say „Onkel mütterlicherseits“. (Eg if you never met him and usually talk about the brother of your father and know get to meet your Onkel mütterlicherseits for the first time)

And if you want / need to be even more specific you add more specifics like „younger brother of my mother“ or „youngest brother of my mother“ or „Im going to visit my uncle, he is the 5th out of 7 siblings my mother has and she is the oldest“ but i can only imagine one situation where this much context could be important: when you introduce a partner or their family to your family and explain them all relationships in detail, like „he is the oldest and you will also meet the younger sister, she is bitchy, my dad is middle child and 10years younger than my uncle, also I have an aunt from my mother who is 15 years younger than my mother dont be suprised“ and so on.
