The full form of Kotlin is not an acronym; it is simply the name of the programming language. Kotlin is a modern, statically typed programming language developed by JetBrains, designed to be fully interoperable with Java and run on the Java Virtual Machine (JVM). It can also be compiled to JavaScript or native code for building cross-platform applications.

Kotlin is widely used for developing Android applications and has gained popularity due to its simplicity, safety features, and conciseness compared to Java. It was officially endorsed by Google for Android development in 2017.
