Morphology

fallacious = fallacy (transparent) = fallacy + ous

The adjective is a regular derivation from the noun 'fallacy' with the adjectival suffix '-ous', so a learner who knows 'fallacy' can infer the meaning.

Etymology

Fallacious comes from the Latin word fallax, itself from fallere meaning 'to deceive'. So a fallacious idea is like a false or deceptive idea that tries to trick you, which is why it is misleading.
