Morphology

microgravity = gravity (semi-transparent) = micro + gravity

The term is built transparently from 'micro' and 'gravity', but the scientific sense is specialized and not fully predictable from the component meanings alone.

Etymology

Microgravity combines the prefix micro- ('small'), like in microscope, with gravity ('weight' or 'pull'), so it literally means a very small pull of gravity and explains why objects float or feel weightless.
