A complete language is not created. All languages evolved, even in the English language. What use to be "hot" (like he's a hot dude) is now "cool".
Theres always a begining, the only thing is, how could the others understand, well never know, and...
unfortunatley theres always an end 2.
see link "Evolution and Changes in Language"
Languages were created through a process of humans communicating with one another over time and developing common methods of expressing ideas and concepts. As early human societies grew, languages evolved and diversified to meet the needs of different peoples and cultures. Over time, languages developed unique systems of grammar, vocabulary, and sounds that reflected the experiences and perspectives of the communities that spoke them.
English was "created"--natural languages evolve, they aren't created. Something like Klingon is a created language, English is a natural language--by people living on the British Isles approximately where England is now.
Swahili is a language that was created with a mix of Bantu languages and Arabic influences. It originated in the African Great Lakes region and has become a lingua franca in East Africa.
It is difficult to determine the exact number of languages because languages constantly evolve, new languages are being created, and some languages are endangered and may not be well-documented. Additionally, there is no universal definition of what constitutes a distinct language versus a dialect or variation.
There is no real-life "Elvish" language like the ones created by J.R.R. Tolkien for his fictional works such as "The Lord of the Rings." However, fans have created languages inspired by Tolkien's Elvish languages, such as Quenya and Sindarin.
Creole languages are actually based on a mixture of different languages, including Spanish and French, but they are not exclusively a blend of those two languages. Creole languages have developed in various parts of the world where people of different linguistic backgrounds have interacted and created a new language to communicate.
