gibbousness
State of swelling
Gibbousness is the quality of being gibbous—swollen, humped, or convex.
The word appears most often in astronomy, describing the phase of a moon or planet when more than half but less than all of its visible surface is illuminated: the gibbousness of the waxing moon.
Outside astronomy, it can describe any rounded protuberance or humpbacked shape.
