Past Tense of Sweat | Explanation & Examples

The past tense of sweat in most cases is sweated, although some dictionaries also allow sweat.

Sweat is a verb and noun, both of which refer to the bodily function of perspiration. As a verb sweat sometimes also describes any process that releases water from an object (e.g., “First, sweat the onions and garlic in a pan”). It can have a negative connotation when used figuratively (e.g., “The river sweats oil and tar” from T. S. Eliot’s The Waste Land).

Because sweat is associated with strenuous exercise, it has come to be a synonym for hard, sustained effort even when there is no actual perspiration (e.g., “You’ll have to sweat it out to pass your exams”).
