progress: [15] Progress is one of a large family of English words (including also grade, gradual, transgress, etc) that go back to Latin gradus ‘step’. From it was derived the verb gradī ‘go, step’, which in combination with the prefix prō- ‘forward’ produced prōgredī ‘go forward’. English gets progress from its past participle prōgressus. => grade, gradual, ingredient, regress, transgress
