Morphology

constriction = constrict (transparent) = constrict + ion

The noun is formed by standard suffixation from the verb 'constrict' and directly denotes the act or result of constricting.

Etymology

The word constriction comes from con- ('together') and strict (a part that means 'to tighten'), like you see in strict and string. So a constriction is when a passage or pipe is pulled tight or made narrower, stopping or slowing the flow.
