Morphology
weightlessness = weightless (transparent) = weight + less + ness
Formed by 'weight' + '-less' -> 'weightless' (adjective), then nominalized with '-ness'; the literal meaning matches the scientific sense.
Etymology
Weightlessness comes from the word weight and the parts -less (meaning 'without') and -ness (making a state). So it literally means 'the state of being without weight', like astronauts who float in space when gravity does not pull them down.
