Robert Gore Posted over 3 years ago Choosing the scientifically best language for international use? You seem to have forgotten Esperanto which was designed to be an easy to pronounce and use European SECOND language. It has simple standard plurals, regular verbs, regular numbers, takes the dominant forms or commonest word roots for its words and does not use letter combinations that are hard or confusing for those of particular mother tongues. It uses a trick to make learning the vocabulary simply, by using suffixes and affixes added to a root word to express related concepts. For example in English we have, kintergarten, primary school, college, university, teacher, pupil, master, student, undergraduate, lecturer, etc etc etc. In Esperanto the method would be like this, take a root like 'learn', then there would be, learnerplace, biglearnerplace, learner, advancedlearner, qualifiedlearner, learnerinstructor, littlelearner. Looks ugly transposed to English, but in Esperanto, where the affixes are short and apply to all other root words it looks and sounds fine. A few core root words and the standard set of add ons, gives a huge vocabulary for a small amount of memorising, When children learn Esperanto at school, it builds confidence in reading, learning other languages, and boosts intelligence, because all the randomness, speculation and uncertainty is removed because all vowel sounds are regular, all pronounciations and spellings are certain, and no plurals or tenses endings can be wrong. The fear of being wrong is removed. No more of the, 'one mouse two mice', 'one sheep two sheep', 'one cow two cows', nonsenses, or 'I am, you are, he is', 'you will be', complexities. Never was introduced for political reasons, but there is a dedicated band of about 6,000,000 speakers worldwide who carry on in hope.
