The word for today is…
indoctrinate (verb):
1 : to imbue with a usually partisan or sectarian opinion, point of view, or principle
2 : to instruct especially in fundamentals or rudiments
Source : Merriam -Webster
Etymology : Indoctrinate means “brainwash” to many people, but its meaning isn’t always so negative. When the verb first appeared in English in the 17th century, it simply meant “to teach”—a meaning linked closely to its source, the Latin verb docere, which also means “to teach.” (Other offspring of docere include docile, doctor, document, and, of course, doctrine). By the 19th century, indoctrinate was being used in the sense of teaching someone to fully accept only the ideas, opinions, and beliefs of a particular group.
