Etymology: Acuity starts life as a verb in Latin. "Acuō" meant "sharpen," and it comes from "acus," a needle or pin, so the core image is something made pointed enough to pierce. The Medieval Latin noun "acuitas" was built from that root, and it carried the plain physical sense of sharpness, the quality of a blade or point. The word reached English through Middle French "acuité" and entered Middle English as "acuite" or "acuyte." Its move from the edge of a tool to the edge of perception happened gradually: sharpness of a point became sharpness of the senses, so a person with acuity could see or hear keenly, and then could grasp matters quickly and precisely. The word is one of several English terms built on the same needle-sharpening root. Its close relatives show the same pattern, since many words for sharpness or keenness began as descriptions of something literally pointed and were later applied to thought and sensation.
