Keening

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

The keening wail of the baby echoed through the nursery, causing concern among the caregivers.

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

The young child stood by the graveside, keening for his pet dog that had passed away.

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