Being mid air is a state of being suspended off the ground, with gravity working against you. The antonyms for this would be being grounded or being stationary. Being grounded refers to the state of being firmly on the ground, where gravity is working in your favor, allowing you to walk or stand with ease. Being stationary refers to the state of not moving or being at rest, where one is not in motion or flying through the air. Both of these antonyms offer a sense of stability and security, which can be a reassuring feeling compared to the uncertainty of being mid air.
