Homonym: Dense (Thick)
"Dense" refers to the compactness of a substance, indicating how much mass is contained in a given volume. For example, materials like lead are considered dense because they have a high mass relative to their size, while substances like foam are less dense due to their lighter structure.
In a broader context, "dense" can also describe something that is difficult to understand or complex, such as a scientific text filled with intricate concepts. In this sense, a dense piece of writing may require more effort to comprehend compared to clearer, more straightforward material.
