Morphology

illogical = logical (transparent) = il + logic + al

The negative prefix 'il-' is a regular allomorph of 'in-' before 'l' and straightforwardly negates the adjective 'logical'.

Etymology

The word illogical starts with the part il-, which means 'not', and ends with logic, which means 'reason' or 'clear thinking'. So illogical means 'not reasonable' and describes something that 'does not make sense'.
