What is the phase of the Moon called when more than half of it is visible between its first and last quarters?

The phase of the Moon called gibbous occurs when more than half of its surface is illuminated by the Sun, but it is not yet full. This phase can be observed after the first quarter when the Moon is waxing, and before the last quarter when it is waning. During these times, the majority portion of the Moon that faces Earth appears bright and round, but a small section remains in shadow, distinguishing it from a full moon, where the entire visible disk is illuminated. Understanding Moon phases is essential for gaining insight into lunar cycles and their impact on various natural phenomena.
