The Vietnamese word "dày cộm" refers to something that is thick and coarse. It is often used to describe materials that have a substantial thickness and a rough texture, such as fabrics or papers.
In more advanced contexts, "dày cộm" can also imply sturdiness or durability. For example, when referring to a book or a notebook, it can suggest that the item is not only thick but also made of quality material that can withstand wear and tear.
While "dày cộm" primarily describes physical attributes of materials, it can also be used metaphorically to describe something that has a lot of substance or depth, like a "dày cộm" argument or discussion.
