Sense: adjective/1
Squeaky, high-pitched, shrill, creaky, and scratchy can all describe unpleasant sounds, but they point to different qualities. Squeaky usually suggests a small, thin sound caused by rubbing, pressing, or poor lubrication, as with a toy, wheel, or chair. High-pitched is more neutral and only tells you that the sound is high. Shrill adds a stronger idea of sharpness and can sound piercing or annoying, especially with voices or alarms. Creaky is rougher and lower, often linked to old wood or metal. Scratchy often describes a rough voice or a sound with friction. Compare: "The suitcase wheel sounded squeaky" versus "The old floorboards sounded creaky."
Etymology
Squeaky comes from the older English verb squeak plus the adjective ending -y. The base verb was first used for short, sharp cries or rubbing noises, and the adjective later described things that make that sound. The sports sense developed metaphorically for a win that gets through by only the smallest margin.
