Morphology
aberrational = aberration (transparent) = aberr + al
The adjective is formed regularly from the noun 'aberration' with the suffix '-al', and the sense of 'deviating from the normal' follows directly from that base.
Etymology
The word aberrational comes from Latin parts ab- 'away' and err- 'to wander', the same root you see in error. So it paints a picture of someone or something 'wandering away' from the usual, and that's why aberrational means 'unusual' or 'not typical'.
