impact




The noun impact can refer to a physical force (like a collision), an influence (a bad role model or a hero), or a strong effect (a foot of snow will have an impact on driving conditions).

Impact is used most often as a noun. A good teacher might have an impact (influence) on a struggling student. The moment two comets collide is called the “moment of impact.” But this versatile word can also be used as a verb, though many people prefer to use its synonyms instead: “affect,” “bear upon,” or “touch on.” Impacted teeth are wedged together or stuck behind each other.
