'directly' originates from Latin, specifically the word 'directus,' where 'di-' meant 'apart' and 'rectus' meant 'straight.' 'Link' originates from Old Norse, specifically the word 'hlankr,' meaning 'a chain or connection.'

'directus' transformed into the Old French word 'direct,' and eventually became the modern English word 'directly.' 'Hlankr' transformed into the Middle English word 'linke,' and eventually became the modern English word 'link.'

Initially, 'directly' meant 'in a straight line,' but over time it evolved into its current meaning of 'without intermediary.' 'Link' initially meant 'a physical connection,' but now also refers to abstract connections.
