Drive home a point
English Idiom
Meaning: To make sure someone understands something completely, often by emphasizing it strongly and repeatedly. This action is done to ensure clarity and to leave no room for confusion.
Origin: The phrase 'Drive home a point' originates from the idea of driving a nail into a piece of wood until it is firmly embedded. Just as a nail is hammered in repeatedly to secure it in place, a point or idea is emphasized repeatedly to ensure it is understood and remembered.
