'appreciate' originates from Latin, specifically the word 'appretiāre,' where 'ad-' meant 'to' and 'pretium' meant 'price' or 'value.'

'appretiāre' transformed into the Old French word 'aprecier,' and eventually became the modern English word 'appreciate' through Middle English.

Initially, it meant 'to set a price on,' but over time it evolved into its current meanings of 'to value' and 'to be grateful for.'
