Age, epoch, era, period all refer to an extent of time. Age usually implies a considerable extent of time, especially one associated with a dominant personality, influence, characteristic, or institution: the age of chivalry. Epoch and era are often used interchangeably to refer to an extent of time characterized by changed conditions and new undertakings: an era ( or epoch ) of invention. epoch sometimes refers especially to the beginning of an era: the steam engine—an epoch in technology. A period may be long or short, but usually has a marked condition or feature: the glacial period; a period of expansion.
First recorded in 1225–75; (for the noun) Middle English, from Anglo-French, Old French aage, eage, equivalent to aé, eé (from Latin ae(vi)tās “age, lifetime,” from aev(um) “eternity, period, time” + -itās -ity ) + -age -age; verb derivative of the noun
Middle English < Old French < Latin -āticum, neuter of -āticus adj. suffix; an extension of Latin -āta -ate 1, whose range of senses it reflects closely
Your age is the number of years you've been alive. If your cat is six, you can say that he's "six years of age." You can also talk about a stage of life or an era in history as an age: "School age kids need to get outside and play every day." Often when someone mentions age as a concept or idea, they mean old age, or being elderly. And the verb age means "grow older." The word comes from the Old French aage, "age or lifetime," from the Latin root aevum, "lifetime, eternity, or age."
