IPA: /rɪˈvaɪvəlɪzəm/
KK: /rɪˈvaɪvəlɪzəm/
A movement or desire to bring back or restore ideas, practices, or styles from an earlier time, often related to religion or culture.
The revivalism of the 19th century brought back many traditional practices and beliefs.
Revivalism is formed from "revival" (from Latin "revivare", meaning to live again) and the suffix "-ism" (meaning a doctrine or belief system). The term refers to a movement or belief system focused on the revival or renewed interest in something, often in a religious context.
Think of 'living again' ('revivare') and how '-ism' indicates a belief system — revivalism is about a belief in bringing something back to life or prominence.
