The idiom "zero in on" means to focus or direct one's attention on something very precisely and accurately. It is often used when talking about targeting a specific goal or objective, or when trying to find a solution to a problem.
For example, if you are searching for a lost item in your house, you might say "I'm going to zero in on the living room because that's where I was last night." This means that you will focus your search on that specific area, rather than searching the entire house.
Another example could be in a business meeting, where a team is discussing a new project. The team leader might say "Let's zero in on the key objectives of this project so we can create a clear plan of action." This means that the team will focus their attention on the most important goals of the project, in order to create a successful plan.
Overall, "zero in on" is a useful idiom to use when you want to emphasize the importance of focusing your attention and efforts on a specific target or goal.
