IPA: /ɪnˈkʌlkeɪtə/
KK: /ɪnˈkʌlkeɪtər/
A person who teaches or instills an idea, habit, or principle in someone else, often through repetition or persistent instruction.
The teacher acted as an inculcator, helping her students understand the importance of honesty.
Inculcator → It is formed from "in-" (meaning into) and "culcare" (meaning to tread or press). The word refers to someone who instills or impresses ideas or values into someone else, as if treading them into the mind.
Think of someone 'pressing' ('culcare') ideas 'into' ('in-') another person's mind — that's why inculcator means a person who instills ideas.
