Morphology

up + in + the + air

The literal words ('up', 'in', 'air') give a clear image of something floating or not grounded, so learners who know the constituents can plausibly infer a sense of being unsettled. However, the specific meaning 'not yet decided' is a metaphorical extension rather than a directly compositional meaning, and its idiomatic use may not be fully predictable without prior exposure.

Etymology

Up in the air may come from the image of something left floating high in the sky and not fixed to anything. Because it is not steady or held down, people use up in the air to mean 'not decided'.
