'synthesis' originates from Greek, specifically the word 'synthesis', where 'syn-' meant 'together' and 'tithenai' meant 'to place'.

'synthesis' changed from the Greek word 'synthesis' into Late Latin 'synthesis' and then appeared in Middle English as 'synthesis', eventually becoming the modern English word 'synthesis'.

Initially, it meant 'a putting together' (the act of placing together), but over time it evolved into its current meaning of 'a combining or forming of a whole from separate parts' and related senses in science and philosophy.
