This reference book is aimed at all learners of Portuguese, whatever their level. Designed for continuous reading or as a grammar dictionary for occasional reference, it offers a structured and accessible approach to the grammatical mechanisms of Portuguese. By highlighting the logical structure of the language, it makes it easier to understand by presenting its key points in a summarised way, illustrated with examples. Thanks to the links established between French and Portuguese, two Romance languages that share many similarities, French-speaking learners will be able to grasp Portuguese grammar in a more intuitive and natural way.
