The phrasal verb "zero in on" is commonly used more in informal speech than in formal contexts, though it can be adaptable depending on the context and audience. It generally means to focus closely on a particular subject, target, or detail, often with the implication of intensified scrutiny or analysis. In everyday usage, it can be applied in various scenarios, such as in discussions about finding solutions, concentrating on specific tasks, or identifying targets in a competitive or strategic setting. It conveys a sense of narrowing down to an essential aspect, often after broad consideration. In business or technical settings, it may appear in strategic discussions or analytical reports to signify precision and focused attention, although typically, a more formal equivalent like "concentrate on" might be chosen in highly formal texts.
