Keening

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 keening shriek of the fireworks lit up the night sky.

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.
