Evection (noun)
e-vek-shun
a periodic irregularity in the moon’s motion, caused by the attraction of the sun.
Evection, “a periodic irregularity in the moon’s motion,” comes from Latin ēvectiō (stem ēvectiōn-) “a going upwards, flight.” Ēvectiō is based on the verb ēvehere “to carry forth, move forth,” from ē (or ex) “out of, from, beyond” and vehere “to carry, drag.”
