Plural of absorbency; the degree or capacity to which something can absorb liquid or other substances.
From absorbent (Latin absorbens, present participle of absorbere) plus -cy (forming nouns), then pluralized with -ies. A technical term used in materials science and engineering.
Different materials have wildly different absorbencies—cotton can hold 27 times its weight in water, while that's why baby diapers use super-absorbent polymers instead of just plain cotton!
