Morphology

fallaciousness = fallacious (semi-transparent) = fallacious + ness

The noun is transparently formed from the adjective 'fallacious' with '-ness', but the adjective's relation to 'fallacy' involves orthographic change and the less obvious suffix '-ious', which may not be fully transparent to learners.

Etymology

The word fallaciousness comes from the Latin root fall- meaning 'to deceive' and is related to the English word false. So fallaciousness is the quality of being 'deceptive' or based on a wrong idea, which is why we use it for bad or mistaken reasoning.
