Etymology: "Senescences" is simply the plural of "senescence", which denotes the gradual ageing process in which a living organism's cells and bodily systems deteriorate over time. The plural form is typically used when discussing several distinct cases or instances of this process, such as the separate ageing trajectories of different tissues or species. The noun "senescence" is formed from "senescent", meaning growing old, with the suffix "-ence" attached. "Senescent" itself comes from the Latin verb "senescere", "to grow old", which is built on "senex", "old man" or "old". The suffix "-ence" turns the adjective into a noun for the state or process being described, so the whole word literally names the condition of becoming old.
