Of the thirty years of the third edition of Learning to translate, ten are new. While some focus on issues already covered in the first two editions, others are looking at new problems: acronyms, signs and panels; with the prepositions and with it and on. Two compound exercises that purpose are specifically devoted to the question of language levels at which the previous editions had not given the attention it deserves. Elsewhere in the manual was replaced or modified translate all phrases that were outdated; it also brought to the explanatory introductions certain exercises changes designed to make them more comprehensive, clearer and more effective. All exercises therefore include some new elements. The manual of the contemporary lexicon is and will be useful to the student, not only in the dissertation and other courses, but also in everyday conversation. Thus rejuvenated, Learning to translate much better meet the current needs of students and those of their teachers.
