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

'appretiāre' transformed into the French word 'apprécier,' and eventually became the modern English word 'appreciate,' from which 'appreciably' is derived.

Initially, it meant 'to set a price or value on something,' but over time it evolved into its current meaning of 'to a noticeable or significant degree.'
