donatio propter nuptias → donation on account of marriage, dowry
προγαμιαία δωρεά, πρὸ γάμου δωρεά
DONATIO PROPTER NUPTIAS. The meaning of this term is explained in the Institutiones (2.7 §3). It was originally called Donatio ante nuptias, because it could not take place after the marriage; but when it was made legal to increase the donatio after marriage, and even to constitute it altogether after marriage, the more comprehensive term donatio propter nuptias was used
