IPA: /ˈkætɪˌkɪzəm/
KK: /ˈkætɪˌkɪzəm/
A book or manual that explains the basic principles of a religion, especially Christianity, often in a question-and-answer format.
The church uses a catechism to teach children about their faith.
Catechism → It is formed from 'catechize' (from Greek 'katēkhizō', meaning to instruct orally) and the suffix '-ism' (meaning a practice or system). The word 'catechism' refers to a system of instruction, particularly in religious education, often through questions and answers.
Think of 'instructing orally' ('katēkhizō') as a way to remember that 'catechism' is about teaching or learning through a structured system.
