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 character in the novel was portrayed as a keening figure, forever yearning for redemption and forgiveness.

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

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