Keening

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

The abandoned puppy let out a keening howl, desperately yearning for someone to rescue it.

The wounded animal emitted a keening cry, pleading for help.

The widow sat alone in her empty house, keening softly for the husband she had lost.

The keening howls of the wolf pierced the silence of the night.

The keening shriek of the fireworks lit up the night sky.
