ingredient

ingredient: [15] The -gredi- of ingredient represents the Latin verb gradī ‘step, go’ (whose past participial stem gress- has given English aggression, congress, digress, etc). From it was formed ingredī ‘go in, enter’, whose present participle ingrediēns became English ingredient. The word’s etymological meaning is thus ‘that which “enters into” a mixture’. It was originally used mainly with reference to medicines, and its current application to food recipes seems to be a comparatively recent development.
=> aggression, congress, grade, gradual
