Pinpoint is a compound word that derives from "pin" (a thin piece of metal with a sharp point at one end and a round head at the other) and "point" (a particular spot, place, or position in an area or on a map, object, or surface).
Although the first usage of the compound word is recorded in the 1840s as a noun simply meaning the point of a pin, the verb and adjective sense is thought to have derived from military aviation slang. Specifically, it was first used by World War 1 bomber pilots and navigators in the sense of locating targets from the air, thus giving pinpoint its association with accuracy.
Pinpoint is still used in this military context. The extreme accuracy of modern weapons systems has meanwhile given a whole new meaning to the adjective pinpoint (US forces launch pinpoint strikes on Iraqi targets).
Still, pinpoint has many more uses outside of the military to describe locating something with accuracy or fine detail, such as pinpointing the causes of a disease, pinpointing the reasons for a company's success (or failure) or the ability of dogs to pinpoint many things with their highly accurate sense of smell.
