absorb

 [ab-sorb´]
1. to take in or assimilate, as to take up substances into or across tissues, e.g., the skin or intestine.
2. to stop particles of radiation energy so that their energy is totally transferred to the absorbing material.
3. to retain specific wavelengths of radiation incident upon a substance, either raising its temperature or changing the energy state of its molecules.

ab·sorb

(ab-sōrb'), Do not confuse this word with adsorb.
1. To take in by absorption.
2. To reduce the intensity of transmitted light.
[L. ab-sorbeo, pp. -sorptus, to suck in]
