The phrasal verb "zone out" is predominantly used in informal contexts, often appearing in casual conversations rather than formal writing or speech. It typically describes the act of losing focus or becoming mentally disengaged from one's surroundings, often unintentionally. "Zoning out" may occur in situations where someone is bored, tired, or distracted, leading them to drift into their thoughts, tuning out external stimuli. This expression is commonly used among friends or in relaxed settings to convey that someone was not paying attention, such as in meetings, classes, or during lengthy conversations. Additionally, "zone out" can be associated with mindfulness discussions, where the opposite is encouraged, i.e., staying mentally present. It is widely understood in both American and British English, though its precise usage might have slight variations across different English-speaking regions.
