The term "modules of elasticity" in wood refers to the ability of the wood to regain its original shape after undergoing stress. This property is crucial in understanding how wood behaves under different loads and environmental conditions. When a force is applied to wood, it deforms; however, the module of elasticity indicates how effectively it can return to its initial form once the stress is removed. This characteristic is essential for assessing the performance of wood in construction and other applications, as materials with a higher modulus of elasticity can withstand greater forces without permanent deformation.

On the other hand, while the ability to absorb moisture, the structural integrity under compression, and the total weight of wood are relevant characteristics, they do not directly define the concept of modules of elasticity. Each of these attributes relates to wood's physical or mechanical properties, but they do not encompass the specific ability of wood to recover its shape after being stressed.
