Etymology
'airspace' originates from the combination of 'air' and 'space', where 'air' refers to the invisible gaseous substance surrounding the earth, and 'space' refers to a continuous area or expanse.
'airspace' was formed by combining the words 'air' and 'space' in the 20th century to describe the navigable atmosphere.
Initially, it meant 'the space above the ground', but over time it evolved to specifically refer to the controlled atmosphere for aviation.
