Keening

The keening screech of the brakes startled the pedestrians on the busy street.

The old woman's keening wails pierced the quiet night, mourning the loss of her husband.

The patient lay in the hospital bed, his keening thoughts consumed by the desire to be healthy again.

The keening sound of the foghorn guided ships safely through the thick mist.

The mother's keening could be heard as she grieved over the loss of her child.
