In general, a Namespace is an abstract container, which is or could be filled by names, or technical terms, or words, and these represent (stand for) real-world things.

As a rule, names in a namespace cannot have more than one meaning, that is, two or more things cannot share the same name. A namespace is also called a ConTeXt, as the valid meaning of a name can change depending on what namespace applies. Names in it can represent objects as well as concepts.

Each Language is a namespace, whether it is a natural or ethnic language, a constructed language, the technical terminology of a profession, a dialect, a sociolect, or an artificial language (e.g., a programming language).

For many programming languages, a namespace (programming) is a context for identifiers.

Within limited namespaces designed for your family, you might be named as Charlie. Within a larger namespace containing strangers as well, the name Charlie might not be unique, so you are instead Charlie Brown, 17 Main Street. In (the namespace of) a family, multiple occurrences of the name Charlie might be differentiated by suffixes such as Sr or Jr .
