n. the capacity of a material to take in and retain liquid or gas. Often used in technical contexts to describe the properties of filters, textiles, or geological formations.
The paper towels have high absorbency.
The manufacturer improved the absorbency of the new fabric to make it more effective for cleaning.
Geologists measured the soil's absorbency to determine how quickly water would drain after the heavy rainfall, which is critical for predicting flood risk.
From absorbance + -y.
