Why the collection of objects in the definition of set is used however empty/one element set is also a set?

Question

In math the definition of a set is “The collection of well defined and distinct objects is called a set" but a set having no element is called a set or a single element set is also called a set however these are not collection of objects. Please explain it. Thanks.

Answer 1

one word can have multiple meanings.  the mathamatical "set" is used differently than the one you are reffering too.....gotta love the english language
