The international language Esperanto was first released to the world in 1887, when L. L. Zamenhof published his first book, “Dr. Esperanto’s International Language”. Since that time, many learning books have been developed to help the beginner attain a proficiency in the language. Helen Fryer’s “Esperanto Teacher” is one of the earliest of these attempts in English. Divided into 45 short and easy lessons and supplemented with sections on joining words, exclamations, compound words, arrangement of words in a sentence, words used with the object, the 16 rules of grammar and list of common useful expressions, as well as a number of translated texts for the new Esperantist to practice his/her skills, this book contains everything one needs to gain a proficiency in the language.
