If you are a learner of English and are buying school supplies for your child, you need to be aware that a ‘composition’ book is not a ‘book’ in the normal sense of ‘book’, as in ‘library book’, but simply a conveniently bound set of blank pages for the student to write in as directed by the teacher. Composition books are available in the school-supplies section of the store.
