Conlanging, short for "constructed language," is the practice of creating a new language from scratch or modifying an existing one. This can involve developing unique grammar rules, vocabulary, and pronunciation. Conlangs can be created for various purposes, including artistic expression, linguistic experimentation, or as part of fictional worlds, such as those seen in J.R.R. Tolkien's Elvish languages or George R.R. Martin's Dothraki. Many conlangers enjoy the challenge of making their languages feel authentic and functional. They often share their creations with others through online communities or publications. Some conlangs, like Esperanto, were designed for international communication, while others, like Klingon from Star Trek, serve specific cultural or entertainment purposes.
