The book includes some "strange" but useful grammatical phenomena that persist and accumulate in the process of learning the French language, such as objects stacked in a real attic.

These specific grammatical phenomena, which often function as obstacles to language use, both in written and spoken discourse, are presented in alphabetical order so that they can be selected independently, according to learning priorities.

The appendix includes supplementary information for recognizing Hellenized Greek words, nouns, adjectives, as well as basic conjunctions and expressions in the French language.

This book can also be used in the classroom as supplementary material for teaching the corresponding phenomena.
