Etymology: "Acuities" is the plural of "acuity," which names sharpness of perception, whether of the eye, the ear, or the mind. The noun descends from Latin "acuō," meaning "to sharpen," the same root behind "acute" and "acumen." Its path into English ran through Medieval Latin "acuitas" and then Middle French "acuité" before arriving in Middle English as "acuite" or "acuyte." The plural is the form readers will meet most often in discussions of different kinds of sharpness, such as visual acuities or auditory acuities, where each sense is measured separately. Each plural names one particular sharpness, so the word's abstract sense of keen insight rests on the same physical image of a point made fine by sharpening.
