'refuel' originates from the prefix 're-' meaning 'again' and the word 'fuel', which comes from Old French 'fouaille', meaning 'firewood'.

'refuel' changed from the Old French word 'fouaille' and eventually became the modern English word 'fuel', with 're-' added to indicate repetition.

Initially, it meant 'to supply with firewood', but over time it evolved into its current meaning of 'to supply with fuel'.
