A more thorough explanation:

Funeral expense refers to the cost of a funeral, including the services and products provided by a funeral home or other service provider. This can include things like the casket, burial plot, embalming, and other related expenses.

Fungibles res is a Latin term used in civil law to refer to things that are interchangeable with other property of the same kind. For example, corn and wheat are considered fungible goods because they can be traded for one another, while land is not fungible because each piece of land is unique and cannot be exchanged for another piece of land.

Fungible is an adjective used to describe something that is interchangeable with other things of the same kind. For example, if you have two identical apples, they are fungible because you can trade one for the other without any difference in value. However, if you have a piece of art, it is not fungible because each piece of art is unique and cannot be exchanged for another piece of art.

Example: If you have two $20 bills, they are fungible because they have the same value and can be exchanged for one another. However, if you have a $20 bill and a $50 bill, they are not fungible because they have different values and cannot be exchanged for one another.
