'suppressor' originates from Latin, specifically the word 'suppressor,' where 'sub-' meant 'under' and 'premere' meant 'to press.'

'suppressor' changed from the Latin word 'suppressor' and eventually became the modern English word 'suppressor'.

Initially, it meant 'one who presses down,' but over time it evolved into its current meaning of 'a device or gene that suppresses something'.
