'impending' originates from Latin, specifically the word 'impendere,' where 'in-' meant 'upon' and 'pendere' meant 'to hang.'

'impendere' transformed into the French word 'impender,' and eventually became the modern English word 'impending' through Middle English.

Initially, it meant 'to hang over or threaten,' but over time it evolved into its current meaning of 'about to happen.'
