ocultar
/okulˈtaɾ/ · A2 · verb
to hide, to conceal
🙈 ocultar = occult: Latin occultare, to keep hidden; the occult is hidden knowledge
English occult comes from the same Latin root, occultus, meaning hidden or secret. So ocultar is simply to make something occult: to hide or conceal it. Astronomers still say one body occults another when it blocks it from view.
