'detectably' originates from the Latin word 'detectare,' where 'de-' meant 'down from' and 'tectare' meant 'to cover.'

'detectare' transformed into the Old French word 'detecter,' and eventually became the modern English word 'detect' through Middle English.

Initially, it meant 'to uncover or reveal,' but over time it evolved into its current meaning of 'to notice or perceive.'
