squeal

A squeal can be the high-pitched sound a pig makes, but it can also happen when someone gives away a secret, like a child who squeals on a friend. It can also describe a loud, sharp cry of protest or excitement. Think of a child squealing with delight on a roller coaster.

The sound itself suggests something sudden and piercing. A rusty gate might squeal as it opens, and tires might squeal when a car brakes hard. Sometimes, to squeal means to inform on someone, often under pressure. "He was threatened with jail time unless he squealed on his accomplices."

The word "squeal" has a versatile range of meanings, all stemming from the idea of a high-pitched, piercing sound. Most literally, it describes the sharp cry made by certain animals, such as pigs or mice. It also describes the jarring noise produced by mechanical friction: "The old swing set squealed with every push."

Beyond physical sounds, "squeal" often describes an outburst of emotion—usually excitement, delight, or even a sudden protest. A child might squeal with joy when receiving a gift, or a fan might squeal at the sight of their favorite celebrity. This usage emphasizes the suddenness and high intensity of the vocal reaction.

More figuratively, to "squeal" means to reveal information, often secrets or incriminating details, usually under duress. This is where the word takes on a negative connotation. Someone who "squeals" on another person is seen as betraying a trust, often to save themselves from trouble. In a criminal context, you might hear: "The suspect squealed to the police in exchange for a lighter sentence."

Finally, "squeal" is also used for the sound of tires skidding or brakes being applied hard, emphasizing that high-pitched, jarring quality of rubber on asphalt. Whether it's an animal's cry, a burst of excitement, a betrayal of trust, or the screech of a car, to squeal usually suggests something sharp, sudden, and hard to ignore.
