Etymology
Origin of subside
First recorded in 1640–50; from Latin subsīdere, from sub- sub- + sīdere “to sit down, settle” ( see also sit 1)
Explanation
To subside is to die down or become less violent, like rough ocean waves after a storm has passed (or your seasickness, if you happened to be sailing on that ocean). Subside comes from the Latin prefix sub- (meaning "down") and the Latin verb sidere (meaning "to settle"). Subside is often used when a negative situation has improved significantly. For example, violence, disease, and unemployment can all subside. Here's hoping that they do.
