https://www.indifferentlanguages.com/words/marriage So exactly how are words like "brak","avioliitto", "santuoka", and 'sib yuav", just to name a few, derviced from "mater"? These are all words that mean marriage. Or do those words not matter? Words come from a lot of sources across many languages. Marriage is an institution, and the word associated with it varies. It is the institution that is more relevant than any one given word. The use of the word source is a red herring.
