Which Latin term means 'and others' and is used for multiple owners?

The Latin term that means 'and others' is "Et al." This phrase is commonly used in legal and academic contexts to refer to multiple authors or owners without having to list all their names. In property assessments, it is particularly useful when acknowledging multiple property owners or parties involved in a transaction without the need for excessive detail, thus streamlining communication and documentation.

The other terms listed do not convey this particular meaning. "Et cetera" translates to 'and the rest' or 'and so on,' but it is typically used to indicate additional items in a list rather than multiple individuals or owners. "Id est," meaning 'that is,' is used for clarification purposes and does not relate to ownership. "Alter ego," which means 'other self,' often refers to a different version of a person or entity, usually in legal situations concerning liability, but is not related to the concept of multiple ownership. Therefore, "Et al." is the most appropriate choice for indicating multiple owners.
