Morphology

attenuation = attenuate (transparent) = attenuate + ion

The word 'attenuation' is transparently derived from 'attenuate' with the addition of the suffix '-ion' to form a noun.

Etymology

The word attenuation comes from Latin parts ad- meaning 'to' and tenu- from tenuis meaning 'thin', so it originally meant 'to make thin'. That's why attenuation now means making sounds, signals, or other things weaker or less strong.
