Nevertheless, Meeus is careful to explain terms as they are first introduced, such as the synodic period of the Moon (time between successive new Moons), anomalistic month (time between successive perigees), and draconian month (time between passages through a node).
After an eclipse cycle, which corresponds approximately to 223 synodic months, 242 draconic months and 239 anomalistic months, the Moon-Earth-Sun geometry will be nearly equal.
