The process of teaching someone to accept a set of beliefs or ideas without questioning them.
The school was criticized for its methods of indoctrination in the classroom.
Indoctrination → It is formed from "in-" (meaning into) and "doctrina" (from Latin, meaning teaching or doctrine) and the suffix "-tion" (meaning the action or process of). The word refers to the process of teaching or instilling a doctrine or belief into someone.
Think of 'teaching' ('doctrina') something 'into' ('in-') someone — that's why indoctrination means instilling beliefs.
