A language runtime is the environment in which a computer program written in a specific programming language is executed. It provides the necessary services and resources for the program to run, such as memory management, garbage collection, and interaction with the operating system. The runtime environment is typically composed of a virtual machine or an interpreter, along with a set of libraries and tools that support the language's features.

For instance, the Java Runtime Environment (JRE) includes the Java Virtual Machine (JVM) and standard class libraries, enabling Java programs to run on various platforms. Similarly, the .NET Common Language Runtime (CLR) manages the execution of programs written in languages like C#, VB.NET, and F#. Interpreted languages like Python and JavaScript also have their respective runtimes, which translate and execute the code line by line or in small chunks.

The primary goal of a language runtime is to abstract away the underlying hardware and operating system details, allowing developers to focus on writing code. It often provides features like Just-In-Time (JIT) compilation, which can improve performance by compiling code into machine code during execution. Runtimes also play a crucial role in ensuring program stability and security by managing resources and preventing common errors. The choice of a language runtime can significantly impact a program's performance, portability, and development experience.
