'refocus' originates from the prefix 're-' meaning 'again' and the word 'focus' from Latin 'focus' meaning 'hearth' or 'fireplace'.

'focus' transformed from the Latin word 'focus' and eventually became the modern English word 'focus'.

Initially, it meant 'hearth' or 'fireplace', but over time it evolved into its current meaning of 'center of interest or activity'.
