petrify

This word is not always about turning something into real stone, even though that is where it started. In everyday English, it usually means to scare someone so much that they feel frozen and cannot move or think clearly. Imagine seeing a dark figure in an alley; the sudden fear could leave you standing still on the spot.

The older, literal meaning is "to turn into stone." That is why Medusa from Greek mythology is such a clear example: her gaze could turn living things into rock. In real life, we use the word mostly for fear, but the image is the same. Someone is so afraid that they seem like stone for a moment, unable to act.

The word "petrify" has two main meanings, and both are built around the idea of becoming like stone. In its literal sense, it means to turn something into stone or into a stone-like state. This is the idea behind petrified wood, where the original material is gradually replaced by minerals over a long time. The word comes from roots that mean "stone" and "make."

In modern conversation, however, "petrify" is most often used to describe frightening someone so badly that they cannot move or think for a moment. It is a strong word, so it does not fit a small surprise. It suggests fear so intense that the person is figuratively turned to stone. For example: "The sudden roar petrified her," or "He was petrified when he heard the noise behind him."

The word can also appear in broader figurative writing to suggest something becoming hard, fixed, or unable to change, though that use is less common than the fear-related one. Most learners will meet it in stories, conversations, and descriptions of fear. Whether it refers to wood becoming stone over time or a person freezing in sudden terror, the central idea is the same: something loses movement and becomes rigid.
