Quick answer: “Change of Heart” means A reversal of one's feelings or decision, driven by emotion.
Change of heart — a reversal of one's feelings, attitude, or decision, usually driven by emotion rather than logic; a shift in what someone wants or believes.
Origin & History
The phrase draws on the ancient and widespread belief that the heart is the seat of human emotions and moral character. A "change of heart" therefore implied a genuine transformation of the inner emotional or moral self, not merely a logical reconsideration. The concept appears in religious texts across many traditions — the Bible, for example, uses the idea of a changed heart to describe spiritual conversion or repentance.
In everyday English usage, the phrase became common from at least the 17th century onwards. Today it is used in a much broader sense to describe any significant reversal of feeling or preference — not necessarily a spiritual one. It is particularly common in personal and political contexts, where someone changes their mind about a relationship, a plan, or a stance after an emotional shift. Reference works such as the Cambridge Dictionary catalogue thousands of such figurative expressions, showing how idiomatic meanings take shape over time.
