To blow out or expel air forcefully; to breathe out with exertion.
From Latin ex- (out) + sufflare (to blow or puff). The word literally means 'to blow out' and appears in medical and physiological contexts.
This is the technical verb for what happens when you exhale forcefully—doctors use it when describing how the lungs expel air, making it sound far more clinical than 'breathing out.'
