Keening

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

The old haunted house echoed with the keening cries of unseen spirits.

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

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.
