'inadvertently' originates from Latin, specifically the word 'inadvertentem,' where 'in-' meant 'not' and 'advertentem' meant 'turning the mind to.' 'Thrown away' is a phrasal verb in English, where 'throw' means 'to cast' and 'away' indicates 'removal or distance.'

'inadvertently' changed from the Latin word 'inadvertentem' and eventually became the modern English word 'inadvertently.' 'Thrown away' has been used in English since the Middle Ages to describe the act of discarding something.

Initially, 'inadvertently' meant 'not turning the mind to,' but over time it evolved into its current meaning of 'accidentally or unintentionally.' 'Thrown away' has largely retained its original meaning of 'discarded.'
