Another interesting artificial language is interlingua. Interlingua is very easy to learn for many people in Europe since interlingua words are taken from English, French, Italian and Spanish. Interlingua is a pragmatic solution for a common language across Europe. As a native spanish speaker I was able to understand about a thousand words in one or two hours studying it. Esperanto is like Haskell, interlingua is like C, one is pure with universal rules for derivation, the other is for using the language from the first day for communication.
