In lumber terminology, "grade" specifically refers to the quality of the wood, which is assessed based on the presence of defects, overall appearance, and characteristics that determine its suitability for various applications. Higher-grade lumber typically has fewer knots, splits, or other imperfections, making it more desirable for visible applications such as furniture and cabinetry. Understanding lumber grades is crucial for carpenters, as it influences both the aesthetic appeal and structural integrity of the final product.

The other options do not accurately encompass the definition of lumber grade. For example, the color of the wood can vary widely within the same grade and is not a determining factor for its classification. Similarly, weight does not correlate directly with quality or grade; different species of wood can have different weights even within the same grade. Lastly, the age of the lumber is not directly tied to the grading system, as lumber can be of excellent quality regardless of its age, depending on the growth conditions of the tree and how it has been processed.
