My heart sank
Meaning
To feel a sudden wave of disappointment, despair, or sadness.
Origin
The vivid image of a 'sinking heart' draws its power from the universal human experience of sudden despair, where one's spirit seems to plummet like a heavy stone. While the exact idiom 'my heart sank' became common in English around the 18th century, the metaphorical connection between the heart—long considered the seat of courage and emotion—and a downward movement representing a loss of hope or vitality can be traced back much further. It personifies the heart as losing its buoyancy, collapsing under the weight of unwelcome news or a sudden realization, making its meaning immediately graspable and timeless.
Examples
- When I saw the notification that my flight was cancelled, my heart sank, knowing I'd miss the meeting.
- Her heart sank as she realized she had left her passport at home, just minutes before boarding.
