Definition: The term 'Catégorie: Toutes les catégories' is a French-based term that means 'All categories'. It refers to a category hierarchy structure where each level reflects the specificity of its corresponding items. For example, the 'Categories: Categorisés par le type' (in English, 'Categories: Grouped by category') may be used for specific categories of products or services. This structure is helpful in categorizing products or services into broad and detailed groups that can be easily understood and searched for.
