Morphology

perturbance = perturb (transparent) = perturb + ance

Formed by the verb 'perturb' plus the noun-forming suffix '-ance'; the sense 'a disturbance' is directly derived from the verb.

Etymology

Perturbance comes from Latin parts per- 'completely' and turbare 'to disturb', the same root as in turbulent. So a perturbance is a disturbance that upsets a system or process.
