Morphology

absorption = absorb (transparent) = absorb + ion

The scientific sense (material taking up energy/substance) directly follows from 'absorb' as 'take in'.

Etymology

Absorption comes from the Latin verb absorbere, meaning 'to suck in'. Like a dark cloth taking in light or a sponge taking up water, absorption in science is one material taking in energy or another substance.
