'condense' originates from Latin, specifically the word 'condensare,' where 'con-' meant 'together' and 'densare' meant 'to make thick.'

'condensare' transformed into the French word 'condenser,' and eventually became the modern English word 'condense' through Middle English.

Initially, it meant 'to make thick or dense,' but over time it evolved into its current meaning of 'to reduce in volume or size.'
