absorbent
ub-ZOR-bunt
/əbˈsɔːrbənt/
Able to soak up liquid, moisture, or light easily and effectively.
Refers to internal liquid retention capacity within porous fibers.
The story behind the word. Comes from Latin 'absorbere', combining 'ab-' ('from') and 'sorbere' ('to suck up'). In English, it originally described physical liquids soaking into porous materials like sponges, but later expanded to describe mind absorption, light absorption, and financial costs.
