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

'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 make more compact or concentrated.'
