- n. An artificial relationship between persons of different blood, regarded as analogous to consanguinity; the relation between families or individuals created by intermarriage (excluding that between the married persons), by legal adoption, or by sponsorship; more especially, the relation between a husband or wife and the kindred of the other spouse. In the Jewish, Roman, and canon laws, affinity by marriage or adoption is a bar to marriage within certain degrees, equally with consanguinity; and on this ground rests the prohibition of marriage with a deceased wife's sister in Great Britain. The canon law treats unlawful sexual intercourse as creating the same affinity with marriage. The relationship of godparents and godchildren, called
spiritual affinity, is not now considered a bar to marriage, as it was before the Council of Trent, which made no provision on the subject.

“How could two chemists converse on chemistry without the use of the term affinity, and the theoretical conception it involves?”
“Yes; but the term affinity is objectionable in this case, because, as that word is used to express a chemical attraction (which can be destroyed only by decomposition), it cannot be applicable to the slight and transient union that takes place between free caloric and the bodies through which it passes; an union which is so weak, that it constantly yields to the tendency which caloric has to an equilibrium.”
