Definition
This set phrase means 'to engrave deeply on one's heart' — a vivid metaphor for remembering something forever, often a lesson, favor, or vow. It is used as a verb phrase in formal or literary contexts, carrying strong emotional weight. Unlike a plain 'remember' (记住 or 记得), 铭记在心 implies a conscious, enduring commitment not to forget.
