Keening

As the fog rolled in, a keening foghorn warned ships of the treacherous rocks ahead.

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

The keening aroma of freshly baked bread wafted through the bakery.

The lonely lighthouse emitted a keening beam of light that swept across the dark sea.

The chilling keening of the banshee sent shivers down the spines of those who heard it.
