'obelisk' originates from Greek, specifically the word 'obeliskos,' where 'obeliskos' meant 'small spit or pointed pillar.'

'obeliskos' changed from the Greek word 'obeliskos' and eventually became the modern English word 'obelisk'.

Initially, it meant 'small spit or pointed pillar,' but over time it evolved into its current meaning of 'a tall, four-sided, narrow tapering monument.'
