Volapük

For those people who claim that Esperanto (the second major constructed language) is too terribly difficult to learn and use, consider the case (no pun intended) of the first-ever constructed language Volapük. It has 19 consonents and 8 vowels (roughly corresponding to German vowels). Not so bad... yet. Now let's look at the verb. Volapük verbs are totally regular and take on different forms based on number, gender, person, tense, mood, and voice. There are a possible 505,440 forms of each verb, although only 351 simple forms ("Blueprints for Babel: the web geek's guide to artificial languages and why you've never heard of them" calls the Volapük system of verb conjugation "one of the most complicated ever devised"). Now let's move on to nouns. There are five different declensions for the nominative, accusative, dative, genitive, and vocative cases; and of course, there's a plural for each one of these declensions. This leaves us with 10 different possible formations of each noun. The language is conveniently agglutinative, and derives its vocabulary from primarily Germanic sources. Now let's look at a sample text of Volapük. „Napoleon äbinom son lavogela Bonaparte baonik ab no liegik. Nag ilefulom studis omik su jul militik in Paris, päcälom as liötan känemik. In tim ot älemom oke, de fenigs pespalöl pokagloki silefik, cinüfadi badik e nedelidik, kel äskanom omi levemo in vigs balid. Ven mon ädefom liötane pöfik kelos ofen äzitos, äpanom gloki oma.” from „NAPOLEONA POKAGLOK” To me, this language is the best form of encryption available today.
