'aggradation' originates from Latin, specifically the word 'aggradatio,' where 'ad-' meant 'toward' and 'gradus' meant 'step or degree.'

'aggradatio' transformed into the French word 'aggradation,' and eventually became the modern English word 'aggradation' through Middle English.

Initially, it meant 'to build up or increase in layers,' and this meaning has largely remained the same in modern usage.
