Keening

The keening stench of decay emanated from the garbage dumpster, making it difficult to pass by.

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

The abandoned graveyard was filled with the keening of the wind passing through the tombstones.

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

The keening tone of his voice conveyed the depth of his heartbreak.
