Etymology

Origin of depression

First recorded in 1350–1400; Middle English (from Anglo-French ), from Medieval Latin dēpressiōn- (stem of dēpressiō ), Late Latin: “a pressing down,” equivalent to Latin dēpress(us) + -iōn- noun suffix; see depress, -ion

Explanation

The act of pressing down on something is called making a depression, and when people suffer from psychological depression that is often what it feels like — the world itself is pressing down on them. Depression can be a persistent mood (rotten), an economic situation (the worst), or just the geography (low). The Great Depression was when poor policy and economic circumstances combined to create a long period of time everyone struggled to even get food on the table.
