affinity

A relationship by marriage. Countries generally have rules prohibiting marriage between certain people where there is an affinity - for example between parents and their step-children (subject to certain unusual exceptions, eg when the step-child was not brought up in the same household as the step-parent). Such prohibitions also apply where there is consanguinity (a blood relationship).
