man's brother

Many languages have terms for siblings that define whether one is younger or older in relation to another sibling.

The Greek that is translated as “a man’s brother” in English is translated in Chilcotin as “ˀeyen ya ˀeŝqi ˀatalilh gwech´ez bunagh” (“a younger brother who was born after [a man] his older brother”). (Source: Quindel King)
