Constructed Language - What does it mean when a language is constructed?

Answer

The term "conlang" describes a language that has been deliberately produced by one or more people. Some examples of such languages are Esperanto, Klingon, and Dothraki. A conlanger is someone who develops a language like this. Otto Jespersen, a linguist, coined the phrase "constructed language" in his 1928 book "An International Language."
