Distraction is a word that describes something that diverts attention or causes someone to lose focus. Some synonyms for the word distraction include interference, interruption, disturbance, diversion, disturbance, and nuisance. When someone or something interrupts a person's work, we can say that person is being sidetracked or derailed. Similarly, when something hampers or impedes a person's concentration or engagement, we use the terms disturbance or disruption. Diversion or amusement, on the other hand, suggests an escape from the tedium or severity of a situation, albeit temporary, while a nuisance denotes something that is annoying or bothersome. Ultimately, the word you choose depends on the specific context and the degree to which the person is being affected.
