To spend from one's savings; to use accumulated money instead of earning new income.
From dis- (opposite/negation) + save. This economic term emerged in the early 20th century as economists needed language to describe drawing down savings accounts.
Economists use dissave to describe when people tap their savings during retirement or tough times—it's the opposite of saving, but more specific than just 'spending.' Nations can dissave too, through budget deficits.
