running on empty positive

Morphology

running + on + empty

The meaning can be partly derived from 'running' (operating/continuing) and 'empty' (having nothing), so a learner who knows the words could infer someone is functioning despite lacking fuel or energy. However, the expression is a metaphorical transfer from vehicles to people and the prepositional pattern 'on empty' is somewhat idiomatic, so the full sense may not be completely predictable without prior exposure.

Etymology

Running on empty comes from cars: a car can keep running when the fuel tank is empty, but it has almost no fuel left. So when people use it now, they mean someone is 'having no energy, resources, or fuel left'.
