'inquisitiveness' originates from Latin, specifically the word 'inquisitio,' where 'in-' meant 'into' and 'quaerere' meant 'to seek.'

'inquisitio' transformed into the Old French word 'enqueste,' and eventually became the modern English word 'inquisitive' through Middle English.

Initially, it meant 'to seek or search,' but over time it evolved into its current meaning of 'curiosity or eagerness to learn.'
