A specter is a ghost or ghostly figure, something that appears faint, pale, and threatening. In spooky stories, a specter might drift through an old mansion's hallways at midnight, barely visible but definitely there. The word suggests something frightening and unnatural, not a friendly spirit but an ominous presence.

The word also describes something threatening that haunts people's thoughts even when it isn't physically present. A family living through a drought might worry about the specter of famine, meaning the very real fear of running out of food hangs over them like a ghost. A country might face the specter of war, meaning the threat feels close and terrifying even if fighting hasn't started yet.

When something spectral appears, it looks ghostly or phantom-like: pale, transparent, or barely visible. You might describe a thin morning fog as spectral, or say that moonlight gives the trees a spectral look.

The word captures that feeling when something frightening seems to be lurking just out of sight, whether it's an actual ghost in a scary story or a serious threat that keeps people awake at night.
