Set: Also known as

In the original translation by Jourdain of Georg Cantor's original work, this concept was called an aggregate. The term can be seen in subsequent works, but has now mostly been superseded by the term set.

Sometimes the terms class, family, system or collection are used. In some contexts, the term space is used. However, beware that these terms are usually used for more specific things than just as a synonym for set.

On this website, the terms class, family and space are not used as synonyms for set, being reserved specifically for the concepts to which they apply.
