Morphology

unperturbed = perturbed (transparent) = un + perturb + ed

The negative prefix 'un-' directly negates the adjective 'perturbed' (disturbed), yielding the clear meaning 'not disturbed'.

Etymology

Unperturbed starts with un- meaning 'not' and the rest comes from perturb, which means 'to disturb' and is like turbulent ('rough' or 'upset'). So unperturbed means 'not disturbed', calm and not worried even when things go wrong.
