• Modern English (1500–Present): Negative developed from Latin through French and related European usage. Impact entered English through Latin, with early senses connected to striking or pressing against something. Over time, impact also came to mean an effect or influence. Today, negative impact commonly describes a harmful effect in education, science, business, health, and everyday life.
