Epoch
noun /ˈiːpɒk/ — A distinct period of history defined by notable events.
Definition
A particular period of time marked by distinctive characteristics or events — often a period long enough to have a character of its own, punctuated by defining moments at its beginning and end.
Beyond the definition
An epoch feels different from inside than a year does — it is a block of time with a coherence, a beginning that felt like a beginning and an end that felt like an ending. Some epochs are centuries; some are a decade; some are three years that changed everything. The word asks you to consider time as having shape.
Origin & history
From Greek epoche (a stoppage, fixed point in time), from epechein (to pause, hold). In ancient Greek, an epoch was literally a pause in time — a fixed point from which other times could be measured.
