MARRIAGE PORTION

A marriage portion is the same as a dowry. It is a sum of money, property, or other valuable assets that a bride's family gives to the groom or his family at the time of marriage.

1. In some cultures, the marriage portion is a traditional custom. For example, in India, it is customary for the bride's family to provide a dowry to the groom's family.

2. In medieval Europe, a marriage portion was often given by the bride's family to the groom's family as a way of securing the bride's financial future.

The examples illustrate how a marriage portion is a form of payment made by the bride's family to the groom's family at the time of marriage. This payment can take many forms, including money, property, or other valuable assets. The purpose of the marriage portion is to provide financial security for the bride and to help establish the couple's new household.
