четверою́родный • (četverojúrodnyj)

1. denotes a relative in the same generation as the head noun but three degrees greater in separation

   четверою́родный брат ― četverojúrodnyj brat ― third cousin

   четверою́родный внук ― četverojúrodnyj vnuk ― second cousin twice removed, grandson’s generation

   четверою́родный пра́внук ― četverojúrodnyj právnuk ― second cousin three times removed, great-grandson’s generation

• There is no single equivalent of this term in English. It is applied to close relations (e.g. brothers, uncles, grandfathers) and indicates a relation that is in the same generation as the term being modified, but is three degrees greater in separation in terms of the closest common ancestor. For example, the четверою́родный equivalent of one's brother is one's third cousin, because one has a common father with one's brother, but a common great-great-grandfather with one's third cousin. (Logically, to find the четверою́родный equivalent of a given relation, find the nearest common ancestor, go three generations up, and then go three generations back down, following different children.) See the table at двою́родный (dvojúrodnyj) for more information.
