A more thorough explanation:

RATIONABILE ESTOVERIUM

Rationabile estoverium (pronounced rash-ee-nay-buh-lee es-toh-veer-ee-uhm) is a legal term that means "reasonable necessaries." In history, it referred to alimony, which is the financial support that one spouse pays to the other after a divorce or separation.

For example, if a husband and wife were getting a divorce, the court might order the husband to pay his wife a certain amount of money each month as alimony. This money would be considered a rationabile estoverium, or a reasonable necessary, to help the wife support herself after the divorce.

Another example might be if a parent was ordered to pay child support to their ex-spouse. This child support would be considered a rationabile estoverium because it is a reasonable necessary to help support the child.

The examples illustrate how rationabile estoverium was used historically to refer to alimony and child support. In both cases, the court ordered one party to pay the other a certain amount of money each month to help support them. This money was considered a reasonable necessary, or a rationabile estoverium, because it was necessary to help the recipient support themselves or their child.
