enXes is based on an unconventional philosophy of language instruction. The great secret to learning Spanish is not just vocabulary, it's grammar. Most English-as-a-first-language (EFL) speakers think about their sentence structure in an intuitive way. Most can't even name the parts of speech, let alone define the rules of grammar. Even getting them to agree that there are at least three tenses -- present, past and future -- is quite a chore. Imagine their surprise when they learn that Spanish has at least seven discrete tenses, and seven more when the compound tenses are added in. And to make it even more confusing, there are many verbs that do not follow the normal rules and change their form in different tenses. And to top it off, there are a few more forms called "voices" that add another subtle touch to sentence construction.
So here is the unconventional approach:
Why is it unconventional? because it actually requires some effort. It's not easy to learn an entire language, just like it's not easy to learn to play the piano. Both require hard work, both in theory and in practice.
How does enXes help?
These types of learning activities augment the more usual conversational Spanish lessons by exercising vocabulary recall and encouraging rapid grammatical construction.
enXes is designed to be used as an unobtrusive aid while reading, hence the sobriquet Pocket Companion. But it's also useful on the street to rapidly produce a conversational term in Spanish or look up the English definition of an object whose name you see written in a store window.
