Keening

The keening sound of the ambulance pierced through the silence of the night.

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.

As the casket was lowered into the ground, the mourners erupted in heart-wrenching keening, expressing their sorrow.

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