'irrationally-shaped' originates from the word 'irrational,' which comes from Latin, specifically the word 'irrationalis,' where 'in-' meant 'not' and 'rationalis' meant 'reasonable.'

'irrationalis' transformed into the Old French word 'irrationel,' and eventually became the modern English word 'irrational' through Middle English.

Initially, it meant 'not reasonable or logical,' and over time it evolved to describe forms or shapes that defy logical patterns.
