doubledot

Doubledot is a term that can refer to several distinct concepts depending on the context. In typography and computing, it is most commonly used to describe the colon punctuation mark (:) when it appears twice in succession (::). This sequence has specific meanings in various programming languages and markup languages. For example, in some object-oriented programming languages, the double colon is used as a scope resolution operator, allowing programmers to access members of a namespace or class from a different scope. In other contexts, such as certain markup languages, it might signify a specific type of link or reference.

The term "doubledot" can also be used informally to refer to any instance where a colon is repeated. However, outside of technical fields, this usage is less common. The visual appearance of two dots in a row can also be a design element in art or graphic design, though the term "doubledot" might not be explicitly used to describe it in those instances. The precise interpretation of "doubledot" is therefore heavily reliant on the specific domain in which it is encountered. Without further context, it is often assumed to refer to the typographical or programming usage.
