Emin Gulu, the linguist who speaks 25 languages developed his own method of learning languages based on the alternative grammar he called “Practical Universal Grammar”. He shared his method in his book series called “Any language in 20 days” (“English in 20 days”, “Russian in 20 days”, “Italian in 20 days”, “Spanish in 20 days”, “French in 20 days” and so on). The method mainly works with the cognitive ability of human. The algorithm of properly lined features of language makes the method unique. The workflow involves compliance between method and the practice. The main goal of the method is to establish a fast track between the thinking and the language. According to the author every language has its own core words forming its body, and the learner is taught to think about the learning proses in that direction. The book consists of introduction, vocabulary, grammar and the bonus parts. The introduction part is the explanation of all the parts in the book and gives general knowledge of the linguistic issues and author’s own ideas about the language learning. The vocabulary and grammar is given in the part divided in 20 days. And the last part is bonus part which teaches the additional features of the languages. The method’s purpose is to help the learner to train the sentence structure and grow automatized ability of making sentences. Besides all these nuances the book also has one more method of the author which is called “One language in one text”. This method is new and it is given in the book as a pilot version of it.
