The English word 'spank' generally refers to hitting someone, usually a child, on the buttocks with an open hand. In Bangla, the closest translation would depend on the specific context and the intent behind the action. While there isn't a direct one-to-one translation, words like 'chhar marā' or similar phrases might be used. It's important to consider the cultural implications and potential sensitivities surrounding physical discipline when discussing this term in Bangla.
