Morphology

ruinous = ruin (transparent) = ruin + ous

The suffix '-ous' is a common English derivational suffix used to form adjectives indicating possession or presence of a quality.

Etymology

Ruinous comes from the Latin root ruina, meaning 'a fall' or 'collapse', and it is the same idea as the English word ruin. So something ruinous causes serious damage or ruin, like a fire or storm that brings buildings down.
