natr

The term "natr" can refer to several different concepts, most commonly a programming language or a file extension.

In the context of programming, Natr is a domain-specific language developed by Microsoft for use with its .NET Framework. It is designed for writing code that interacts with natural language and is often used in applications requiring natural language processing or understanding. Natr aims to simplify the development of such applications by providing a more intuitive syntax compared to general-purpose programming languages.

Alternatively, "natr" can be a file extension, often associated with Natural language resources. These files might contain dictionaries, grammars, or other data structures used by natural language processing tools. The specific format and purpose of a .natr file would depend on the software that created it.

Without further context, it is difficult to definitively determine which "natr" is being referenced. The programming language is more widely known in technical circles, while the file extension is more specific to certain software applications.
