'correctly' originates from Latin, specifically the word 'correctus,' where 'cor-' meant 'together' and 'regere' meant 'to guide or rule.'

'correctus' transformed into the Old French word 'correct,' and eventually became the modern English word 'correctly' through Middle English.

Initially, it meant 'to guide or rule together,' but over time it evolved into its current meaning of 'in a manner that is accurate or appropriate.'
