Senescence can be traced back to Latin senex, meaning “old.” Can you guess which other English words come from senex? Senile might (correctly) come to mind, as well as senior.

There’s also the much rarer senectitude, which, like senescence, refers to the state of being old (specifically, to the final stage of the normal life span).
