'discriminator' originates from Latin, specifically the word 'discriminare,' where 'dis-' meant 'apart' and 'criminare' meant 'to separate or distinguish.'

'discriminare' transformed into the Medieval Latin word 'discriminator,' and eventually became the modern English word 'discriminator.'

Initially, it meant 'to separate or distinguish,' but over time it evolved into its current meaning of 'a person or thing that discriminates.'
