Morphology

absorption + coefficient

The meaning — a numerical measure quantifying how much a material absorbs — is directly derivable from combining 'absorption' (the process of taking up energy or a substance) with 'coefficient' (a numerical constant or measure). This noun–noun compositional pattern is regular in technical vocabulary, so a learner who knows both constituents can infer the general sense even if they lack specialized scientific detail.

Etymology

Absorption coefficient comes from absorption (like a sponge taking in water) and coefficient (a number that measures something). So it means 'a number that shows how much light or energy a material takes in as it passes through'.
