Täysveljet
Täysveljet is a Finnish term that translates to "full brothers." It specifically refers to two or more male siblings who share the same biological father and the same biological mother. This term is often used in contexts where the distinction between full siblings and half-siblings is important, such as in genealogical research, legal matters, or discussions about genetics and inheritance. In contrast, half-brothers (puoliveli) share only one biological parent. The concept of täysveljet emphasizes a complete shared lineage from both parents, distinguishing them from siblings who may have a shared parent but not both. The term is straightforward and aims to clearly define a specific familial relationship.
