'alogism' originates from Greek, specifically the word 'alogos,' where 'a-' meant 'without' and 'logos' meant 'reason' or 'logic.'

'alogos' transformed into the Medieval Latin word 'alogismus,' and eventually became the modern English word 'alogism.'

Initially, it meant 'without reason,' but over time it evolved into its current meaning of 'illogical statement or idea.'
