'occurrence' originates from Latin, specifically the word 'occurrere,' where 'ob-' meant 'toward' and 'currere' meant 'to run.'

'occurrere' transformed into the French word 'occurrence,' and eventually became the modern English word 'occurrence' through Middle English.

Initially, it meant 'to run toward,' but over time it evolved into its current meaning of 'an event or instance of something happening.'
