'shall' originates from Old English, specifically the word 'sceal,' where 'sceal' meant 'to owe' or 'to be obliged to.'

'sceal' transformed into the Middle English word 'schal,' and eventually became the modern English word 'shall.'

Initially, it meant 'to owe' or 'to be obliged to,' but over time it evolved into its current meaning of expressing future actions or intentions.
