Nine Frightfully Impressive Words for Your Halloween Vocabulary

I read the dictionary so you don’t have to. The selection below could, in my opinion, be well employed in horror stories and casual Halloween party conversation:
“You look positively sepulchral.”
“Why, thank you!”

Eldritch: Weird, ghostly, unnatural, frightful, hideous. (Of obscure origin. Potentially something to do with elves.)

Gloaming: An Old English word for twilight. (Useful now the latter has become synonymous with sparkly vampires.)

Imbrue: To stain, especially with blood.

Lambent: Of a flame (fire, light): Playing lightly upon or gliding over a surface without burning it, like a ‘tongue of fire’.

Lycanthropy: The transformation into werewolf form.

Mizzle: 1. Misty rain (modern). 2. A sudden or surreptitious departure or disappearance (rare/archaic).

Rutilant: To shine with a reddish glow.

Sepulchral: 1. Pertaining to the tomb or interment. 2. gloomy; dismal. (From the Latin Sepultra: to bury.)

Susurration: Malicious whispering.

Definitions were checked in the OED. Those are just a few words I’ve come across lately and enjoyed. Please add your favourites – leave a comment!
