A pinpoint is an extremely precise spot or location. Imagine trying to find a small target with an arrow - that's roughly what pinpoint means.
The word "pinpoint" is often used when someone needs to be exact about something, like finding a specific address on a map or identifying the source of a problem. For example, if you're planning a party and one guest says they'll be arriving at 8:15 PM sharp, you might say "I've pinpointed the time we need to leave" to show that you know exactly when it is. In medical terms, doctors use pinpoint to describe a precise location of pain or an exact spot on a patient's body where something needs attention.
