👉 Cahier is a type of notebook that is commonly used for writing and organizing notes, ideas, and information. It consists of two sections: the front cover and the back cover. The front cover often contains the date and author's name, while the back cover usually contains additional details such as the size, weight, and page number. Cahiers are typically made from durable paper or cardstock and are commonly used in classrooms, libraries, offices, and other settings for note-taking and organization.
