Brother’s story begins in Proto-Germanic: brōþēr meant “brother.” Matches Latin 'frāter' and Sanskrit 'bhrātṛ'. By 700s-1000s, the word had taken hold in Old English as brōþor. Also used for fellow monks, as Latin 'frāter' was. It reached English by 1500s as brother. The old plural 'brethren' survives for members of a religious community. Today, brother means a son of the same parents as another person.
