pinpoint (n.)

also pin-point, 1849, "the point of a pin," from pin (n.) + point (n.). Taken into aeronautics in a sense of "place identified from the air" (used to ascertain the position of the aircraft); hence the verb meaning "locate precisely" (1917), which originally was aviators' slang. Related: Pinpointed; pinpointing. As an adjective, "performed with precisional accuracy," 1944, originally of aerial bombing.
